Peter was on duty at the Pearly Gates when the bell rang.

He opened up and asked the little, old man, "Who are you?" "I am Albert Einstein. I was told to come here." "Can you prove who you are?" Einstein produced a stick of chalk and scribbled a very long and complicated formula on the gate post.

"That is the mathematical answer to everything." "It certainly is! Welcome Mr Einstein.

" A short while later and the bell rang again.

"I am Pablo Picasso. I was told to come here." "Can you prove who you are?" Picasso picked up the stick of chalk and drew a picture on the other gate post.

"That is a reclining nude.

" "It certainly is! Welcome Mr Picasso." The bell rang a third time.

"I am John Prescott." "Can you prove who you are?" "I've told you! Why the hell have I got to prove it?" "Mr Einstein and Mr Picasso had to, and were able to, prove who they were." "Who the f**k are Einstein and Picasso?" "Ah!! Welcome Mr Prescott"
