If you need a drink of water or something, just get up and get it. Don't even ask, just go and get it.
Now everyone can speak before we have dinner, and of course, we can talk when we have left the dining room after dinner, but once we go into the dining room before we sit down to have dinner, that's it. Nothing can be said until dinner is finished. It won't matter what is done, if you drop anything, or spill something, just leave it, or clean it up if you want, but don't say anything. If you do, you'll be doing the dishes for the next week."
"No problem," he says. And in they go.
The boyfriend is astounded. Right smack in the middle of the living room is a huge stack of dirty dishes. In the family room, another huge stack of dishes. Piled up the stairs, dirty dishes. In fact, everywhere he looks, dirty dishes. And empty boxes, everywhere. Empty boxes that used to contain dinner sets, and cutlery sets. Everywhere, empty boxes. And dirty dishes.
They sit down to dinner and, sure enough, no one says a word.
As dinner progresses, the boyfriend decides to take advantage of the situation.
So he leans over and kisses his girlfriend. No one says a word. So he decides to reach over and fondle her breasts. He looks at her parents, but still they keep quiet.
So he stands up, grabs his girlfriend, strips her naked, and they make love right on the dinner table. Still, no one says a word.
"Her Mom's kinda cute", he thinks. So he grabs his girlfriend's Mom and has his way with her right there on the dinner table. Again, total silence.
Then, a few raindrops hit the window and the boyfriend realizes it's starting to rain. He figures he'd better take care of the motorcycle, so he pulls the Vaseline from his pocket.
Suddenly the father stands up and shouts: "All right, all right! I'll do the damn dishes."
