Sound advice...
If your admission to Heaven is kind of iffy, learn to play the harp before you die.
Because, when you show up at the Pearly Gates with a harp, Saint Peter is bound be impressed and wave you right in. You can skip the harp lessons and be strumming on a cloud the same day.
A coronet might also get you a pass, but beware: there are no accordion players in Heaven, and bag-pipers go straight to Hell.
