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?

He will shave himself once... because before he gives himself his first shave, he will have been a town resident that doesn't shave himself. Upon giving himself his first shave, he now becomes someone who shaves himself, thereby making him unable to give himself a shave.
