The other day I was in the Auto Zone part 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 some how and I need a new one."
"What does it do?"
She said, "I don't know, but its always been there." The Counter Clerk gave her a note pad and asked her if she could draw a picture. So She makes a circle about 3 inches in diameter and in the center she writes 710.
Question: Was she a blonde?
