Flat as a Pancake Puns

A trucker came into  a Truck Stop Café and placed his order with the waitress. He said "I want three flat tires, a pair of headlights and a pair of running boards."

The brand new blonde waitress, not wanting to appear stupid, went to the kitchen and said to the cook, "This guy out there just ordered three flat tires, a pair of headlights and a pair of running boards. What does he think this place is, an auto parts store?"

"No," the cook said.  "'three flat tires' mean three pancakes; 'a pair of headlights' are two eggs sunny side up; and 'a pair of running boards' are 2 slices of crisp bacon!"

"Oh.. OK!" said the blonde. She thought about it for a moment and then spooned up a bowl of beans and gave it to the customer.

The trucker asked, "What are the beans for, Blondie?"

She replied, "I thought while you were waiting for the flat tires, headlights and running boards, you might as well gas up!"

A little context first: What's known as an "apartment" in the US is generally referred to as a "flat" in the UK. My dad lives in a flat and has a cat. Without a doubt any time anyone talks to my dad this exchange happens:

Person: Do you like locally?
Dad: I live in the flats near the river. Just me and my cat.
Person: Oh, you have cat?
Dad: Yes. She's called Pancake.
Person: That's nice, but why did you name her Pancake?
Dad: Because she's not a house cat... she's a flat cat.

Despite the fact that he's proudly said this joke dozens, if not hundreds, of times, he still cracks up as he says it like it's the funniest joke ever invented.
