A man and a barber are talking.

barber: GOD does not exist because if there were GOD, there would be no evil.

The man didn't reply to aviod arguements, then left the shop. Outside he saw a beggar with long, dirty hair. The man went back to the barber shop,

man: You know, barbers don't exist.

barber: Can't you see I'm a barber?

man: If a barber existed, there would be no man with dirty long hair.

barber: It's just that they don't come to me.

Then the man said, "Like GOD, if people would come to Him, there would be no evil.
