A boy is watching television and hears the name Jesus Christ. Wondering who Jesus Christ is, he asks his mother. She tells him that she is busy, and to ask his father. His father is also busy so he asks his brother. His brother kicks him out of the room because he doesn't have time to answer his stupid questions.
So he goes downtown and sees a bum in an alley. He asks the bum, "Who's Jesus Christ?"
The bum replies, "Well, I am."
The boy, not believing the bum, asks for proof. So the bum takes the boy into the bar down the street and takes him inside. They walk up to the bar and the bartender exclaims, "Jesus Christ, are you in here again!?"
