I don't know if this one has been said..but here it is(it is religious though...):
Saint Peter is standing at the gates of Heaven when nature calls. He asks Jesus to take his place and tells Jesus what to do.
After a while, an old man approaches the gates and Jesus proceeds to ask him some questions, "What was your occupation?"
The old man answers, "I was a carpenter."
Jesus asks, "Did you have any children?"
"Well," answers the old man, "I had a son, but he left me a long time ago. He had holes in his hands and feet."
"Father?" asks Jesus surprised.
The old man asks, "Pinocchio?"
