Heard this on Prarie Home Companion: Albert Einstein dies, and goes to meet St. Peter at the pearly gates of heaven. St Peter says "I need to see some ID before I can let you in". Al asks for a chalkboard, which is produced, and the goes on to cover the board with equations describing various aspects of Relativity. After a while, St. Peter stops him and says "Go on in, now I know you are who you say you are". Pablo Picasso dies, and also goes to meet St. Peter at the pearly gates of heaven. St. Peter says "I'm going to need to see some ID before I can let you in". Pablo asks for a canvas, which is produced, then goes on to paint a very modern masterpiece in the Picasso style. After a while St. Peter stops him and says "Go on in, now I know you are who you say you are." George W. Bush dies, and goes to meet St. Peter at the pearly gates of heaven. St. Peter says "I'm going to need to see some ID before I can let you in". W says, "But I was the President of the United States, the most powerful nation on the planet. My face was known to hundreds of millions of people. Why do I have to show ID?" St. Peter says "We need ID from everyone. We needed ID from Einstein, and from Picasso, so we are going to need ID from you as well". W looks puzzled for a moment then asks "Who are Einstein and Picasso"? After a long moments silence, St. Peter says "Go on in, now I know you must be who you say you are."
