One day at St Peter's gate (the entrance to heaven) a 
particularly loved and good pope shows up as he had just passed 
away. 
> 
St Peter: Oh Pope! We are so glad to receive you...because you 
have led such a pious and holy life that any time you want to 
see God you just walk on in without an 
appointment...furthermore, we are giving you the key to 
heaven...with this you can go into any room or area and do 
anything you desire! 
Pope: Fantastic! What I really would like to do is go to the 
library and read the transcripts of what God really said to the 
disciples.  I bet there are some differences between what was 
really said and what the bible says. 
St Peter: Well go ahead. 
So the Pope goes to the library and spends the next 3 years 
doing his research until one day there come the most incredibly 
loud screaming.  Suddenly, St Peter, all the angels and saints 
rush in to find the Pope staring at a page in one of the 
transcripts. 

St Peter: Pope! What is the matter that causes you scream with 
such anguish?? 
Pope: THERE'S AN "R"....THERE'S AN "R"!!! .....all this time it 
was suppossed to say CELEBRATE!!
