A new young monk arrives at the monastery and as with all new monks he is assigned to help the other monks in copying the old canons and laws of the church  by hand.

He notices, however, that all of the monks are copying from copies, not  from the original manuscript. So, the new monk goes to the headabbot to  question this, pointing out that if someone made even a small error in the first copy, it would never be picked up. In fact, that error would be  continued in all
 of the subsequent copies.

The head monk, says, "We have been copying from the copies for centuries, but you make a good point, my son." So, he goes down into the  dark caves underneath  the monastery where the original manuscript is held as archives in a  locked vault that hasn’t been opened for hundreds of years.

Hours go by and nobody sees the old abbot. So, the young monk gets  worried and goes downstairs to look for him.

He sees him banging his head against the wall, and wailing, "We forgot  the "R"! "We forgot the "R"! "We forgot the "R"! "We forgot the "R"!

His forehead is all bloody and bruised and he is crying uncontrollably.  The young monk asks the old abbot, "What’s wrong, father?"

With a choking voice, the old abbot replies, "The word is celebrate!"
