From wikipedia:

"The barber is the 'one who shaves all those, and those only, who do not shave themselves.' The question is, does the barber shave himself? Answering this question results in a contradiction. The barber cannot shave himself as he only shaves those who do not shave themselves. As such, if he shaves himself he ceases to be the barber. Conversely, if the barber does not shave himself, then he fits into the group of people who would be shaved by the barber, and thus, as the barber, he must shave himself."
