A male pastor walked into a neighborhood pub to use the restroom. The place was hopping with music and dancing, until people saw the pastor.

As the room quieted down he 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 pastor asked. "I really need to use a restroom!"
"Well, I don't think you should. There is a statue of a naked woman in there -- and she's only covered by a fig leaf!"
"Nonsense," said the pastor, "I'll look the other way!"

So, the bartender showed the clergyman the door at the top of the stairs, and he proceeded to the restroom.

After a few minutes, he came back out, and the whole place was hopping with music and dancing again! He went to the bartender and said, "Sir, I don't understand. When I came in here, the place was hopping with music and dancing. Then the room became absolutely quiet. I went to the restroom, and now the place is hopping again."
"Well, now you're one of us!" said the bartender. "Would you like a drink too?"
"But, I still don't understand," said the puzzled pastor.
"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?"
