ON A VERY COLD NIGHT
On a very cold night, a young man dropped into the local brothel and the madam said, "You'll have to wait."
"But there's lots of girls that aren't busy right now."
"Yes, but several of the rooms are closed for repairs."
So she takes his money and he goes upstairs with one of the staff and, after looking for a place to consummate the transaction, they decide to do it on the roof. But it's a very cold night, and they freeze to death and fall to the sidewalk.
A passing drunk looks them over, staggers to the door, and knocks. "Go away!" says the madam. "We don't allow drunks in here!" "I don't want in," says the drunk.
"I just wanted to tell you that your sign fell down."
