A guy comes into a coffee shop and places his order: "I want 3 flat tires & a pair of headlights." The waitress, not wanting to appear stupid, goes to the kitchen & asks the cook, "This guy out there just ordered 3 flat tires & a pair of headlights. What does he think, this is an auto parts store?!"
"No," the cook says, "3 flat tires means 3 pancakes & a pair of headlights is 2 eggs sunny side up."
"Oh," says the waitress. She thinks about this and then she spoons up a bowl of beans and gives it to the customer. The guy says "What are the beans for?"
The waitress replies "I thought that, while you're waiting for the flat tires & headlights, you might want to gas up."
