How to Gain admission into Heaven

As the "sinners", all over the world, plan & strategize as to how to successfully enter heaven, here is a joke that shows that you simply need to "prove" your identity!
....................................................................
When Einstein died and arrived at the gates of heaven, St. Peter would not let him in until he proved his identity.
Einstein demonstrated a few of his theories & equations, and was granted admission into paradise. When Picasso died, St. Peter asked, “How do I know you’re
Picasso?” Picasso re-drew a few of his masterpieces. St. Peter let him in. When George W. Bush died, he went to heaven and met the Saint at the entry - “How can
you prove to me you’re George W. Bush?”
Bush countered, “Heck, you don’t know me?” St. Peter replied, “Well, Albert Einstein proved his equations and Picasso drew his famous sketches. What can you do to
prove you’re George W. Bush?” Bush remained stoic, “Who are Albert Einstein and Picasso?” St. Peter smiled, “It must be you, George, hop in.”
