There is a vllage where the barber shaves all those and ones who do not shave themselves who shaves the barber?

This is a paradoxy paradox. You see, if the barber shaves himself, he will be breaking his rule which is he only shaves those who do not shave themselves. He would be shaving himself. But if he didn't shave himself, then he wouldn't be shaving himself and thus he would be able to shave himself.

So the real answer is: If this sentence is not true, then Santa Claus exists.
