Some Irish humor
Two leprechauns approached a convent in Ireland. The one would knock on the door and say:
"Beggin' your pardon, sister. But prey tell, do ya have any nuns as tall as me and my friend here?"
"Ah, no, my lad", the nun would reply, "we surely do not".
The leprechauns left that convent and proceeded to every other convent in Ireland. At each convent, the same response would be given. As they knocked on the last door, they were saddened that, one more time, the answer would be the same.
After they left that last convent, the one leprechaun looked at the other and said: "See, I told you you've been fucking a penguin".
