A blonde walked into a Lordco auto accessory parts store asking for a "710 cover" for her car engine. The man at the counter looked puzzled and told her he had never heard of a 710 cover. She explained that her car had always had one since new, but she noticed it was gone after the last servicing.

After spending an hour checking everything in the parts catalogue and consulting several other staff members, one of the service agents asked her if she could draw a 710 cover.

She held up her hands and made a circle about 2-1/2 inches. He still didn't understand and patiently asked her to draw a picture for him (by that time there were several employees watching the proceedings).

The woman drew a circle (with an edge like a flower) and wrote 710 inside the circle.... All the employees started to laugh - why did they laugh?
