Irish Predicament
 

Drunk Ole Mulvihill (From the Northern Irish Clan) staggers into a
Catholic Church, enters a confessional box, sits down, but says nothing.
The Priest coughs a few times to get his attention but Ole Mulvihill
just sits 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."
