peek at the picture until you have read the following:
few days ago I was having some work done at my local garage when
a blonde came in and asked for a seven-hundred-ten.
all looked at each other and Bob the mechanic asked, "What
is a seven-hundred-ten?"
replied, "You know, that little piece in the middle of the
engine, I've lost mine and need a new one.
gave her a piece of paper and a pen and asked her to draw a picture
of what the piece looked like. She drew a circle and in the middle
of it and wrote 710.
then took her over to another car which had its hood up and asked
"is there a 710 on this car?"
pointed to it and said, "Of course, its right there."
