There were two men in a bar talking and the first man began to tell
the second man a story:

One day St. Peter sent an angel to Earth to make a list of all the
people that were doing hanky-panky. The angel soon found that this
was a monumental task, so he asked St. Peter for some assistance.
However, none could be given due to the labor shortage. So, a
compromise was reached in that the angel would a list of those persons
not engaging in hanky-panky. This was a much shorter list. Upon
returning with the list, the angel was bid of St Peter to send a
letter of commendation to all those on the list that had not
participated in hanky-panky.

At this point the first man turned to the second and asked,And do you
know what the letter said? No, what did the letter say? Ah, so
you didnt get one either!
