Race to the finish
The old king is dying, and wants to leave his kingdom to the wiser of his two sons. He tells them that he will hold a horserace, and the son whose horse is the last to reach the church and come back will inherit the realm. Immediately the younger son jumps on a horse and makes for the church at top speed. The king now knows that this is the wiser son, and leaves him the kingdom. Why?

Boxes of Money
Someone shows you two boxes and he tells you that one of these boxes contains two times as much as the other one, but he does not tell you which one this is. He lets you choose one of these boxes, and opens it. It turns out to be filled with $10. Now he gives you the opportunity to choose the other box instead of the current one (and skip the $10 of the first box), because the second box could contain twice as much (i.e. $20).
The Question: Should you choose the second box, or should you stick to your first choice to maximize the expected amount of money?
Read the hint below if you're stuck...
A Hint: If you have $10, and you could double this with a chance of 1/2, or half it with a chance of 1/2, one would expect an average of 1/2 * $20 + 1/2 * $5 = $12.5 (so you would expect to gain $2.5)!...

A little bit of baseball trivia
(Not that any of this is true in history)
Let's say that Ty Cobb's seaon batting average is the same as Shoeless Joe Jackson's at the beginning of a late-season double-header. Assume both batters have had hundreds of at bats.
Cobb went 7 for 8 (.875) while Jackson went 9 for 12 (.750). But at the end of the day, Jackson's season average turned out to be higher than Cobb's. How is this possible?

Diamonds are forever
Of the four suits that make up a deck of cards, only the diamonds are symmetrical, in that a diamond - unlike a club, a heart or a spade looks the same whether it is rightside-up or updside-down.
However, one of the 13 diamond cards is different when you turn it upside-down. Without checking any deck of cards you may have lying around, can you name that one non-symmetrical diamond?

Solve the mystery
"We've got a mystery", Grandpa said, "the mystery of the missing tea." He went on to explain to his grandson, Junior, that Grandma made sun tea that she left on an upside down crate in the backyard each morning. About twice a week it disappeared. Grandpa suspected Buz, the kid who lived next door, because he had seen him out in the field behind their house two or three times on days when the tea was missing.
After breakfast that day, they went out back to check on the jar of tea Grandma had put out that morning. It was gone. "There's Buz," Grandpa said, pointing to a boy out in the field walking away from them. Junior followed Buz out into the field.
As Junior got closer, he could see Buz had a jar in his hand. It was empty.
"What are you doing?" Junior asked, trying to sound friendly.
"I'm catching bees for my collection," Buz said, looking around as if searching for a little victim. "I almost got that yellow-jacket," he said, indicating a large black-and-yellow-striped bee several yards out of reach.
"Do you know a lot about bees?" Junior asked.
"Oh, yes. I study them. I just that yellow jacket and I'll have an example of all the kinds you see around here. By the way, my name's Buz. Who are you?"
"I'm Junior, the guy who caught you stealing my grandmother's tea," Junior replied.
Why is Junior so sure Buz stole the tea?

A little darker than what I usually post
I am the part of the bird that is not in the sky,
who can drown in the ocean and yet remain dry.
A last vestige of Man that refuses to die.
In mourning I am tossed at your feet to lie;
I begin my Job early, devouring your ankles and thighs.
I Work my way up, eating your legs to your waist.
And though around midday away I am chased,
I return quickly to savor the arm of my taste.
As evening Falls I enter your lungs,
spiraling Down past your mouth and your tongue.
I feast on your body, your soul, and your mind,
but as darkness falls you shall find
that away I will go, a relief for some;
At least until tomorrow morning comes.

Holly Jolly Man
You will know that I am coming
From the jingle of my bell,
But exactly who I am is not an easy thing to tell.
Children, they adore me
for they find me jolly,
but I do not see them when the halls are decked with holly.
My job often leaves me frozen,
I am a man that all should know,
But I do not do business in times of sleet or ice or snow.
I travel much on business,
But no reindeer haul me around,
I do all my traveling firmly on the ground.
I love the time of Christmas,
But that's not my vocational season,
And I assure that is because of a sound economic reason.

This is not a riddle
I've recently put in a feedblitz e-mail delivery system (find it in the syndication section). If you're interested, please sign up and let me know if it's worth having. If you're not interested in having these posts delivered to your e-mail, then please let me know by commenting here.
I think it's a good idea for several reasons. Perhaps you don't have access to the web, say at work? But you still want to expand your brain a little bit by thinking through a riddle. It also lets me know that there are people who are interested in this site (making it worth my while to post everyday). I know there are some 'regulars' who try to answer the question each day, but I think there are more people who get here later in the day and don't want to post after the answer has been given.
BTW, I've implemented this across my blogs, so if you like to read info on Boston Sports, games on the web, etc... please head on over and sign up there as well.
Take some time and sign up. I'd appreciate it.
While I'm at it, if you have another site to recommend for a syndication button, let me know about it. I want to make your experience here as easy and pleasant as possible.

X: "I have no idea what your sum is, Y."
Y: "That's no news to me, X. I already knew you didn't know that."
X: "Ahah! Now I know what your sum must be, Y!"
Y: "And now I also know what your product is, X!"

A caning?
Four gentlemen (Adam, Bill, Chuck, and Dan) went to an expensive restaurant to dine. They checked their coats, hats, gloves, and canes at the door (each of the gentlemen had one of each). But when they checked out, there was a mix up, and each of the men ended up with exactly one article of clothing (a pair of gloves is considered a single article of clothing) belonging to each one of the four. Adam and Bill ended up with their own coats, Chuck ended up with his own hat, and Dan ended up with his own gloves. Adam did not end up with Chuck's cane. State whose coat, hat, gloves, and cane each of the gentlemen ended up with.

Isaac and Albert were excitedly describing the result of the Third Annual International Science Fair Extravaganza in Sweden. There were three contestants, Louis, Rene, and Johannes. Isaac reported that Louis won the fair, while Rene came in second. Albert, on the other hand, reported that Johannes won the fair, while Louis came in second.
In fact, neither Isaac nor Albert had given a correct report of the results of the science fair. Each of them had given one correct statement and one false statement. What was the actual placing of the three contestants?

How many am I?
My first is a number, my second another,
And each, I assure you, will rhyme with the other.
My first you will find is one-fifth of my second,
And truly my whole a long period reckoned.
Yet my first and my second(nay, think not I cozen),
When added together will make but two dozen.

Four jolly men
Four jolly men sat down to play,
And played all night till break of day.
They played for cash and not for fun,
With a separate score for every one.
When it came time to square accounts,
they all had made quite fair amounts.
Now, not one has lost and all have gained -
Tell me now, this can you explain?

I've proven 1 = 2
Or have I?
Here is the proof...
Can you spot the error?
Here is the proof...
(1) X = Y | Given |
(2) X2 = XY | Multiply both sides by X |
(3) X2 - Y2 = XY - Y2 | Subtract Y2 from both sides |
(4) (X+Y)(X-Y) = Y(X-Y) | Factor both sides |
(5) (X+Y) = Y | Cancel out common factors |
(6) Y+Y = Y | Substitute in from line (1) |
(7) 2Y = Y | Collect the Y's |
(8) 2 = 1 | Divide both sides by Y |

Poetry, yes that's right... poetry
Ten weary, footsore travellers,
All in a woeful plight,
Sought shelter at a wayside inn
One dark and stormy night.
'Nine rooms, no more,' the landlord said
'Have I to offer you.
To each of eight a single bed,
But the ninth must serve for two.'
A din arose. The troubled host
Could only scratch his head,
For of those tired men not two
Would occupy one bed.
The puzzled host was soon at ease -
He was a clever man -
And so to please his guests devised
This most ingeneous plan.
In a room marked A two men were placed,
The third was lodged in B,
The fourth to C was then assigned,
The fifth retired to D.
In E the sixth he tucked away,
In F the sventh man.
The eighth and ninth in G and H,
And then to A he ran,
Wherein the host, as I have said,
Had laid two travellers by;
Then taking one - the tenth and last -
He logged him safe in I.
Nine singe rooms - a room for each -
Were made to serve for ten;
And this it is that puzzles me
And many wiser men.

Consider two round coins of equal size. Imagine holding one still so that it does not move and then rolling the other coin around it, making sure that it does not slip. The rims are kept touching at all times. How many times will the moving coin have rotated after it has completed one revolution of the stationary coin?
Don't try it until you have thought about it.

Some literature review, for those who hate math
The paragraph below is most unusual. How quickly can you find out what is so unusual about it? It looks so ordinary you'd think nothing was wrong with it - and in fact, nothing is wrong with it. It is unusual though. Why?
"Gatsby was walking back from a visit down in Branton Hill's manufacturing district on a Saturday night. A busy day's traffic had had its noisy run; and with not many folks in sight, His Honor got along without having to stop to grasp a hand, or talk; for a mayor out of City Hall is a shining mark for any politician. And so, coming to Broadway, a booming bass drum and sounds of singing, told of a small Salvation Army unit carrying on amidst Broadway's night shopping crowds. Gatsby, walking towards that group, saw a young girl, back toward him, just finishing a long, soulful oration ... "
The above passage is taken from the book "Gatsby" written by Ernest Vincent Wright in the late 1930's

A long, metal slide resembling a sliding board has been constructed with 3 holes spaced out along the length of the slide. Coins are placed at the top of the slide and released one after another. For each coin that approaches the first hole the chances are 50 percent that it will fall through the hole. If it makes it past the first hole the chances are 50 percent that it will fall through the second hole. The third hole has the same chances.
How many coins need to be released so that chances are that one coin will make it all the way down the slide?

Multiply or Add?
A customer at a 7-11 store selected four items to buy, and was told that the cost was $7.11. He was curious that the cost was the same as the store name, so he enquired as to how the figure was derived. The clerk said that he had simply multiplied the prices of the four individual items. The customer protested that the four prices should have been ADDED, not MULTIPLIED. The clerk said that that was OK with him, but, the result was still the same: exactly $7.11. What were the four prices?

This is an old one my dad taught me many years ago:
Three people check into a hotel. They pay $30 to the manager and go to their room. The manager suddenly remembers that the room rate is $25 and gives $5 to the bellboy to return to the people. On the way to the room the bellboy reasons that $5 would be difficult to share among three people so he pockets $2 and gives $1 to each person. Now each person paid $10 and got back $1. So they paid $9 each, totalling $27. The bellboy has $2, totalling $29. Where is the missing $1?
