When Einstein died and arrived at the gates of heaven, St. Peter
wouldn't let him in until he proved his identity.

Einstein scribbled out a couple of his equations, and was admitted
into paradise.

And when Picasso died, St. Peter asked, "How do I know you're
Picasso?"

Picasso sketched out a couple of his masterpieces. St. Peter was
convinced and let him in.

When George W. Bush died, he went to heaven and met the man at the
gates. "How can you prove to me you're George W. Bush?" Saint Peter
said.

Bush replied, "Well heck, I dont know."

St. Peter says, "Well, Albert Einstein showed me his equations and
Picasso drew his famous pictures. What can you do to prove you're
George W. Bush?"

Bush replies, "Who are Albert Einstein and Picasso?"

St. Peter says, "It must be you, George, c'mon on in."
