Switch Or Stick Riddle
There are three doors: Door 1, Door 2, and Door 3. Behind one of these doors lies eternal bliss, but behind the others lies eternal despair. You are allowed to choose any door, and you pick Door 1. Suddenly, Door 3 is swung open and revealed to be despair! You are give another choice: you may stick with the door you chose (1) or switch to the other (2). What should you do?
Hint:
The answer may surprise you: switch. Due to something called the Monty Hall Paradox, you will statistically have a better chance of making the "correct" choice. The concept is as follows:
Door 1 Door 2 Door 3
All have an equal chance to be correct:
Door 1: 1/3 Door 2: 1/3 Door 3: 1/3
After choosing Door 1, the remaining two have a 2/3 chance of containing the right choice:
Door1: 1/3 Doors 2 3: 2/3
If Door 3 is removed, the probability does not shift to 50:50. Instead, it is:
Door 1: 1/3 Door 2: 2/3
Thus, you should switch. Did you answer this riddle correctly?

The Liar's Village Riddle
A man is traveling to a town and comes to a fork in the road. If he goes left, he goes to the liars' village. If he goes right, he then goes to the village of truths - which is where he wants to go. However, he does not know which way is which.
He doesn't have time to go both routes, so he approaches a stranger who is standing in the middle of the fork. The stranger says he may only ask 3 questions and he will answer them.
The man asks, "Are you from the village of truths?" The stranger says, "Yes!" However, the man is still facing a dilemma: If the stranger was from the village of truths he can only tell the truth, but if he was from the village of liars, he would say he was from the village of truth.
So then he asks the stranger, "Are you telling the truth?" The stranger says, "Yes!" But sadly this leaves the man in the same position as before.
