Confession?

A drunken man staggers in to 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 mate, there`s no toiletpaper in this one either."
