A: You hit the post and pans with sticks \ Q: Explain this: There is one barber in a town. Everyone goes to that barber. He has a sign in the window that says: Everyone in town will come to me and will not shave himself. No exceptions. So someone was walking along the road one day and the sign caught her eye. She went in and told him that his rule contradicts itself. She tells him that when he wants to shave himself, he can't go to him without shaving himself. He took the sign down.
