A drunken man staggers into a Catholic church and wanders over to the
confessional box. He opens the door, sits down and says nothing. The bewildered
priest waits for a few minutes, allowing the drunken man some time to collect
his thoughts. Growing impatient, the priest coughs to attract his attention, but
still the man says nothing. The priest then knocks on the wall three times in a
final attempt to get the man to speak. Finally, the drunk replies: "No use
knockin pal, theres no paper in this one either."
