A lonely, and horny housewife with her husband out of town on a business trip, goes to a single bar, strikes a conversation with a guy who tells her he's a building contractor and, long story short, she takes the guy to her house. They immediately tore each other's clothes off and started going at it.
Suddenly, she sat up in bed as she heard the key in the lock. "Quick!" she said to the man, "It's my husband! You've got to get out of here! Quick!"
"Where's the back door?", the man asked as he grabbed his clothes. This she replied.
"Where would you like one?" asked the man.
