This is the actual question:
Suppose there is a town with just one male barber; and that every man in the town keeps himself clean-shaven: some by shaving themselves, some by attending the barber. It seems reasonable to imagine that the barber obeys the following rule: He shaves all and only those men in town who do not shave themselves.
It's supposed to illustrate Russell's Paradox.
It's impossible for 2 reasons:
1) If the barber does not shave himself, he must abide by the rule and shave himself.
2) If he does shave himself, according to the rule he will not shave himself.
It's not a riddle it's got no real answer. Riddles have answers. The answer is that it's impossible. Fuck your riddle.
