The other day I was in the local auto parts store, when a lady came in and asked for a 710 cap.
We all looked at each other and said, "What's a 710 cap?" She said, "You know, it's right on the engine. Mine got lost some how and I need a new one." "What kind of a car is it on?," they asked.
Now I'm thinking maybe an old Datsun 710, but no, she said it's a Pontiac.
"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." We gave her a note pad and asked 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 fall down behind the counter laughing so hard they are in hysterics.
(Directions ... draw a circle, write 710 in the middle of it, and turn it around.) Yes, she was a blonde.
