A nun, really needing to go to the bathroom, walked into a
neighborhood pub. The place was hopping with music and
dancing but every once in a while the lights would turn
off. Each time after the lights would go out the place
would erupt into cheers. However, when the revelers saw the
nun, the room went dead silent.

She walked up to the bartender, and asked, "May I please
use the restroom?"

The bartender replied, "I really don't think you should. "

"Why not? " the nun asked.

"Well, there is a statue of a naked man in there, and his
most private part is covered only by a fig leaf. "

"Nonsense, " said the nun, "I'll just look the other way. "

So the bartender showed the nun the door at the top of the
stairs, and she proceeded to the restroom. After a few
minutes, she came back out, and the whole place was hopping
with music and dancing again. However, they did stop just
long enough to give the nun a loud round of applause.

She went to the bartender and said, "Sir, I don't
understand. Why did they applaud for me just because I went
to the restroom? "

"Well, now they know you're one of us, " said the
bartender, "would you like a drink? "

"But, I still don't understand, " said the puzzled nun.

"You see, " laughed the bartender, "every time the fig leaf
is lifted on the statue, the lights go out in the whole
place. Now, how about that drink?"
