There's this guy who's in the market for a used
motorcycle. Always wanted a nice big hog. So he's
shopping around, answering ads in the newspaper,
and not having much luck. One day he comes across
a beautiful classic Harley with a for sale" sign
on it. Upon inspection, he is amazed to find the
bike in mint condition. He inquires about it with
the owner:

"This bike is beautiful! I'll take it. But you
gotta tell me how you keep it in such good shape.
"Well," says the seller, "it's pretty simple.
Just make sure that if the bike is outside and
it's going to rain, rub Vaseline on the chrome.
It protects it from the rain. In fact, since
you're buying the bike I won't need my tube of
Vaseline anymore. Here, you can have it." and he
hands the buyer a tube of Vaseline.

So the guy buys the bike and off he goes, a happy
biker. He takes the bike over to show his
girlfriend. She's ecstatic (being a Harley fan).

That night, he decides to ride the bike over to
his girlfriend's parents' house. It's the first
time he's going to meet them and figures it will
make a big impression. When the couple gets to
the house, the girlfriend grabs her boyfriend's
arm.

"Honey," she says, "I gotta tell you something
about my parents before we go in. When we eat
dinner, we don't talk. In fact, the person who
says anything during dinner has to do the
dishes."

"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. 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 handle 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."
