Blind Man
There was a blind man standing by the road side, begging for loose change. A man passing by gave him a fake £1 coin. Later the man passed by the beggar again. This was what ensued between the man and the blind man:
BLIND MAN: "Sir, you gave me fake money this morning."
MAN:" How did you know it was fake money? Who told you I gave it to you? I think you are not blind. Are you?"
BLIND MAN: "No I am not, I'm begging for my friend who is blind."
MAN: Ok where is he?"
BLIND MAN: "He's at home watching TV."
