One night, a man and his lady friend
were about to enter his apartment, when, before he could open the door, she said,
"Wait a minute, I can tell how a man makes love by how he unlocks his door."
The man says, "Well, give me some examples."
The lady explains, "Well, if a guy shoves his key in the lock, and opens the door hard, then that means he is a rough lover and that isn't for me. If a man fumbles around and can't seem to find the hole, then that means he is inexperienced, and that isn't for me either."
Then she said, "How do you unlock your door?"
The man answered,
"Well, before I do anything else, I lick the lock"
