Not exactly legal. It's smart anyway

A man goes on a night out with his friends the wife becomes furious and tells the kids that when he comes back they must not open the door for him.

At about midnight, the man comes back and knocks. The Wife tells him "Go back and sleep where you are coming from!" Judging by her tone of voice that her fury is about to overflow, the man answers "Relax I'm not here to sleep, I'm here to collect condoms in my room on top of the table or just give them to me. There are lots of pretty women at the party!"

The wife immediatly opened the door and said "You are not going anywhere come in here before I change my mind!"

I don't think that's exactly legal.
