Seven Ten Cap

The other day I was in the local auto parts store. A lady comes
in and asks for a seven ten cap. We all looked at each other
and said, "What's a seven ten cap?" She said "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 on?" they asked.

Now I'm thinking maybe an old Datsun Seven Ten, but no, she
said, "It's a Buick." "OK lady, how big is it?" She makes a circle
with her hands about 3 1/2 inches in diameter. "What does it do?"
we asked. She said, "I don't know but it's always been there."

One of us gave her a note pad and asked her 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. The guys behind
the counter are looking at it upside down as she writes it and
they just fall down behind the counter laughing.
