Pistols at Dawn
You're in a pistol duel with two others. You have shoot with an accuracy of 33%. The other two shoot with an accuracy of 100% and 50%, respectively. The rules of the duel are one shot per-person per-round. the shooting order is from worst shooter to best shooter. Thus, you go first, the 50% guy goes second, and the 100% guy goes third; repeat until only one is left. If someone is hit, we just skip his or her turn. What should you shoot at in round 1 to maximize your chances of survival over time?

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?

Riddles
Since I got such positive feedback on the riddle "Attack!", I thought I'd try a few more:
a) What has 4 legs and flies? (Hint: it's not a dead horse!)
b) How many times can you subtract 6 from 30?
c) What number can you subtract half from to obtain a result that is zero?
d) What English word can have 4 of its 5 letters removed and still retain it's original pronunciation?
e) You have 10 bags of gold coins, 10 coins per bag, 10 grams per coin, but one bag of coins weigh only 9 grams per coin (because of low quality). How do you find out which bag contains low quality gold coins? You may use a scale only one time.
f) How can a woman living in New Jersey, legally marry 3 men, without ever getting a divorce, be widowed, or becoming legally separated?

This is an old one my dad taught me many years ago...
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?

How many pizza toppings are there, anyways?
Let's say you're running a pizza shop and you want to advertise how many different types of pizzas you can make. You have 10 different toppings to use, but of course you can combine them with others to make your pizza. How many pizzas can you make?
BTW, don't worry about people who want 'double' pepperoni.

Game Show
Suppose you're on a game show, and you're given the choice of three doors. Behind one door is a car, behind the others, goats. You pick a door, say number 1, and the host, who knows what's behind the doors, opens another door, say number 3, which has a goat. He says to you, "Do you want to pick door number 2?" Is it to your advantage to switch your choice of doors?
