There's a Nun in Hooters!

A nun, badly needing to use to the restroom, walked into a local Hooters restaurant.
The place was alive with music, loud conversation, and every once in a while the lights would turn off. Each time the lights turned off the place would erupt into thunderous cheers. However, when the revelers saw the nun, the room went dead silent.
The nun walked up to the bartender and asked, "May I please use the restroom?
The bartender replied, "OK, but I should warn you that there is a statue of a naked man in there wearing only a fig leaf! "
"Well, in that case I'll just look the other way" said the nun.
So, the bartender showed the nun to the back of the restaurant, and into the restroom she went.
After a few minutes she came back out and the whole crowd stopped laughing just long enough to give the nun a loud round of applause.
Curious, the nun went to the bartender and said, "Sir, I don't understand. Why did they applaud 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 on the statue is lifted up, the lights go out. Now, how about that drink?"
