Steve's motorcycle has missing seal. So whenever it rains Steve has to smear Vaseline over the spot where the seal should be. One day, his girlfriend invited him over for dinner to meet her parents. So he drives his motorcycle over.
His girlfriend was waiting outside for him when he arrives and says, "No matter what happens at dinner tonight, don't say a word. Our family had a fight a while ago about doing the dinner dishes. We haven't done any since and the first person to speak at dinner has to do them."
Steve sits down for dinner and soon notices that his girlfriend wasn't exaggerating. It is just how she described it. Dishes are piled up to the ceiling in the kitchen and nobody is saying a word.
He decides to have a little fun and grabs his girlfriend, throws her onto the table and has sex with her in front of her parents. His girlfriend is a little flustered, her father is obviously livid, and her mother is horrified. Yet, when Steve and his girlfriend resume their places at the dinner table, nobody says a word.
A few minutes later, Steve grabs his girlfriend's mom, throws her onto the table and does a repeat performance. Now his girlfriend is furious, her father is boiling, and her mother is a little more pleased. But still, there is complete silence at the table.
Suddenly, there is a loud clap of thunder and it starts to rain. Steve remembers his motorcycle outside and so he jumps up and grabs his jar of Vaseline.
With a look of terror in his eyes, the girlfriend's father backs away from the table and exclaims, "Okay, okay, enough already, I'll do the damn dishes!"
