Einstein, Picasso and George W. Bush stand before the Pearly Gates Einstein, Picasso and Bush stand before the Pearly Gates. St. Peter gets out to greet them and says: "I'll let you in, but first you have to prove that you are who you say you are." Einstein: "That's easy. Could you give me a blackboard and some chalk, please?" St. Peter snaps his fingers, a blackboard and chalk appear, and Einstein writes a few formulas while explaining the theory of relativity. "I believe you, it really is you. Welcome to Heaven, Albert!" Picasso: "Give me a canvas, some paint and a paintbrush and I'll prove it." St. Peter makes a canvas appear, and within minutes, Picasso has drawn a masterpiece out of this world. "I'm genuinely impressed. Welcome in Paradise, Pablo!" Picasso high-fives Einstein as they cross the gates together. "Well, Einstein and Picasso both proved their identities. How can you prove yours?" Bush looks puzzled, tilts his head to the side and asks: "Who were these guys?" St. Peter sighs: "Come on in, George."
