In a certain small town, there is a barber named Bill. Since Bill is the only barber in the town, he decides that he will shave all the town's residents who do not shave themselves, but (obviously) not the ones who do.
If Bill follows this rule, will he shave himself or not?
If he shaves himself, then he cannot shave himself. If he does not shave himself, then he has to shave himself. It is a paradox!
