Jesus and Moses are up in heaven sitting around, trying to think of something to do. Moses says, "Hey Jesus, I think it would be fun to go down to earth and perform miracles like in the good old days, what do you think?" Jesus agrees and they head down to earth.
Once they get there, Moses says, "I think what i want to do first is part the red sea, that was a lot of fun." So Moses goes and parts the Red Sea and comes back and says, "That was awesome, what do you want to do, Jesus?"
Jesus thinks for a while and then says, "You know, I really enjoyed walking on water, I think I will do that again." So Jesus goes over to a lake and starts walking across the water. As soon as he starts, though, he begins to sink to the bottom.
He comes back to land disappointed and Moses says, "Well, I guess the last time you did that you didn't have holes in your feet."
