The Pope dies and goes to heaven. He is welcomed by a reception committee and, after a brief tour, is told he can enjoy any of the myriad recreations available.
He decides to read the ancient original texts of the Holy Scriptures. He spends an eon learning languages until he becomes a linguistic master. Finally, in the heavenly library, he begins to pore over every version of the Bible, working his way back from modern translations to the original scripts.
Suddenly, a scream echoes through the library. Angels rush in to find the Pope huddled in his chair, weeping and muttering, "An 'R'! The scribes left out the 'R'!"
A concerned Angel comforts him and asks what he means. The Pope collects himself and sobs, "It's the letter 'R'. They left it out. The word was supposed to be CELEBRATE!"
