What is a 710 knob?
A few days ago I was having some work done at my local garage. A blonde came in and asked for a seven hundred n ten knob?
We all looked at each other and another customer asked, 'What's a seven hundred n ten knob?'
She replied, 'You know, the little piece in the middle of the engine, I have lost it and need a new one.' She said that she didn't know exactly what it was, but this piece had always been there.
The mechanic gave her a piece of paper and a pen and asked her to draw what the piece looked like.
She drew a circle and in the middle of it wrote 710.
Confused he then took her over to another car which had its hood up and asked 'is there a 710 on this car?'
She pointed and said, 'Of course, it's right there.'
