Einstein dies and goes to heaven. At the Pearly Gates, Saint Peter tells him, “You look like Einstein, but you have NO idea what some people will do to sneak into Heaven. Can you prove who you really are?”
Einstein ponders for a few seconds and asks, “Could I have a blackboard and some chalk?” St Peter snaps his fingers and a blackboard and chalk instantly appear. Einstein proceeds to describe with arcane mathematics and symbols his theory of relativity.
Saint Peter is suitably impressed. “You really ARE Einstein!” he says. “Welcome to heaven!”
The next to arrive is Picasso. Once again, St Peter asks for credentials. Picasso asks, “Mind if I use that blackboard and chalk?” St Peter says, “Go ahead.” Picasso erases Einstein’s equations and sketches a truly stunning mural with just a few strokes of chalk.
St Peter claps his saintly hands. “Surely you are the great artist you claim to be!” he says. “Come on in!”

Saint Peter sighs and says, “Come on in, Barnaby.
