Ok, BEFORE you send the hate mail... I married into an Irish-Catholic family, so I'm allowed to "take the micky out" once in a while as the Brits will say. And besides, I thought this one was just too funny to keep to myself. Thanks to Steve Kantor for sharing:

A drunk staggers into a Catholic Church,
enters a confessional booth, sits down, but says nothing.
The Priest coughs a few times to get his
attention but the drunk continues to sit there.
Finally, the Priest pounds three times on the wall.
The drunk mumbles, "ain't no use knockin,
there's no paper on this side either!"
