A couple on their first date decide to go to his place afterwards
When they arrive, before he even gets the house keys out of his pocket, the girl says:
“You know, I can actually tell whether the man I’m dating and I are compatible
based on how he opens the door. If he busts it open, it means that he’s a selfish lover,
and that’s definitely not someone I’m interested in. If he drops the keys,
it means that he’s inexperienced in bed, and that’s not who I’m looking for either.
So how do you open the door?”
“Well”, says the guy, “I’ll just lick the lock first, if you don’t mind.”
