I read this joke in a book a couple of months ago and was in one of those situations where before I could do anything I was the guy on the subway laughing uncontrollably. Now I have had a couple of different reactions to it. I wasn't sure whether or not a written joke would be funny said out loud. Some people laughed as hard as I did, some guffawed, some smiled enjoying the joke, and one person said "I don't get it." And after explaining the joke they said "Yeah, I understand it but I just don't get what's funny." Which stunned the room and got quite a few laughs. Ok, ok, the joke:
One day up in heaven St. Peter has to go and run some errands so he asks Jesus if he would mind watching the gate for the afternoon. Jesus says no problem. Jesus is sitting there and an old man approaches. Jesus says hello, what good things have you done on earth to make you think that you should enter the gates of heaven? The old man says well, it's not so much what I have done. I am but a humble carpenter. But my son, my son brought much happiness and joy to the world and was known and loved by many. At hearing this Jesus throws his arms around the old man and cries out Father! Father! The old man replies Pinocchio?
