Einstein ponders for a few seconds and asks:
- "I can get a blackboard and chalk?
San Pedro snaps fingers and instantly appear a blackboard and chalk. Einstein begins to describe very complicated mathematical symbols his theory of relativity. San Pedro is totally impressed.
- "You really are Einstein!, Welcome to heaven!
The next to arrive is Dali. Again, St. Peter asks for credentials. Picasso asks:
- "Mind if I use that blackboard and chalk this?
- "Go ahead," replied St. Peter
Dali erases Einstein's equations and sketches a mural despanpanante with a few quick strokes of chalk. San Pedro applauds:
- "I am sure that you are the great artist you claim. Inwards!"
Then St. Peter looks up and sees George W. Bush. He scratches his head and says:
- "Einstein and Dali had to prove their identity. How can you prove yours?
George W. is somewhat taken aback and says:
- "Who are Einstein and Dali?"
Saint Peter sighs and says:
- "Welcome, George!"
