The key to happiness

A guy and his date are about to go into his apartment. Before he can open the door his
girlfriend says, “Wait a minute, I can tell how a man makes love by the way he unlocks
the door."
"Interesting” says the guy, “Give me some examples."
"Well, if he shoves his key in the lock, and opens the door hard, then that means he is a
rough lover and isn’t for me. If a man fumbles around and can’t seem to find the hole,
then that means he is inexperienced and isn’t for me. So how do you unlock your door?"
The guy thinks for a minute then says, "Well, before I do anything else could you link
this key?"
