Flip The Switch Riddle
There is a prison with 100 prisoners, each in separate cells with no form of contact. There is an area in the prison with a single light bulb in it. Each day, the warden picks one of the prisoners at random, even if they have been picked before, and takes them out to the lobby. The prisoner will have the choice to flip the switch if they want. The light bulb starts off.
When a prisoner is taken into the area with the light bulb, he can also say "Every prisoner has been brought to the light bulb." If this is true all prisoners will go free. However, if a prisoner chooses to say this and it's wrong, all the prisoners will be executed. So a prisoner should only say this if he knows it is true for sure.
Before the first day of this process begins, all the prisoners are allowed to get together to discuss a strategy to eventually save themselves.
What strategy could they use to ensure they will go free?

Hint:
Only allow one prisoner to turn the light bulb off and all of the others turn it on if they have never turned it on before. If they have turned it on before they do nothing. The prisoner that can turn it off then knows they have all been there and saves them all when he has turned it off 99 times. Did you answer this riddle correctly?

Tommy Pickle's Cousin Riddle
Hint:
The Day Of My Birthday
Hint:
December 31. Let's assume that December 31 is my correct birthday. Now let's also assume that I am 21 and that today is January 1st (the day after my birthday). That would mean that the day before yesterday (December 30) I would be 20. That fits the riddle so far, but here comes the tricky part!
Let's also say that the current year is 2013. So to clarify, today is January 1st 2013. Next year would be 2014, and the trick is that I will have two more birthdays by the end of 2014, one on December 31st 2013 (22 years old) and one on December 31st 2014 (23 years old).So in 2014, the year after 2013, I will actually turn 23! It's a tricky riddle. Best way to go about it is to use trial and error with all the answers and to also keep an open mind about what "next year" means. Did you answer this riddle correctly?
