It is to Laugh (slightly risque)

Joe came across a Harley with a 'for sale' sign on it. The bike was ten years old but in mint condition, shiny without a flaw.

He bought it then asked the seller how he kept the motorcycle is such great shape.

'Well, it's quite simple, really,' said the seller. 'Whenever it's gonna rain, I rub Vaseline on the chrome. That protects it from the rain.'

And he handed Joe a jar of Vaseline.

That night, his girlfriend, Sandra, invited him to meet her parents. Naturally, they take the bike. But just before they enter the house, Sandra stopped him.

'I have to tell you something about my family before we go in. When we eat dinner, we don't talk. In fact, the first person who says anything during dinner has to do the dishes.'

'No problem,' he says. And in they go.

Joe is shocked. In the middle of the living room is a huge stack of dirty dishes. In the kitchen, piled on the countertops are greasy pots and pans. In the corridor, on the stairs, everywhere he looks food-encrusted dinnerware.

They sit down to dinner and, sure enough, no one says a word.

Dinner progressed. Then Joe smirked, leaned over, and kissed Sandra.

Silence. He reached over and fondled her breasts. Still, nobody said a word. So he stood, ripped her clothes off, threw her on the table, and screwed her right there in front of her parents.

His girlfriend is flustered, her dad livid, and her mom horrified as he sits back down. But no one said a word.

He eyed Sandra’s mom. 'She's got a great body,' he thinks. So he grabs the mom, bends her over the dinner table, and has his way with her.

Now his girlfriend is furious and her dad is boiling, but still, total silence.

Into the silent dining room sounds a clap of thunder and it starts to rain. Joe remembers his bike, so he pulls the jar of Vaseline from his pocket....

The father jumped away from the table. “Okay! I'll do the f****** dishes.”
