Joke for today?

[bloocrab]

The other day I was in my local auto part store when a lady comes in
and
asks for a seven ten cap. We all look at each other and ask,
"What's a seven ten cap?"
She says, "You know, it's right on the engine. Mine got lost somehow
and
I need a new one."
"What kind of a car is it?" Joe the counterman ask.
Now I'm thinking maybe an old Datsun Seven Ten, but no, she says that
it's
a
Buick. "Okay, Lady, how big is it?"
She makes a circle with her hands about 3 1/2 inches in diameter.
"What does it do?" I ask.
She says, "I don't know, but it's always been there."
Joe gave her a note pad and asks if she could draw a picture of it.
So she makes a circle about 3 1/2 inches in diameter and in the
center she writes 710.
Joe from behind the counter, was looking at it upside down as she
writes
710...
and he just fall down behind the counter laughing so hysterically.
One of the other guy says, "I think you want an oil cap."
She says, "Seven Ten cap, oil cap, I don't care what you call it. I
just
need
one,
and I don't see what is so damn funny about it."
Yes, she was a blonde, and if you read "710" upside down it reads OIL
