Two broadcast engineers are at the Hooters in Lawrenceville NJ. The first one says to the second that the average person knows very little about basic broadcast engineering. The second one disagrees, and claims that most people can understand a reasonable amount of it.
The first engineer leaves to go to the restroom, and in his absence the second calls over the waitress. He tells her that in a few minutes, after his friend has returned, he will
call her over and ask her a question. All she has to do is answer "ninety nine
point seven and one oh five
point one".
She repeats "99. what"? He repeats "99.7 and 105.1". Her: "997 and 1051"? Yes, that's right, he says. So she agrees, and goes off mumbling to herself, "9 9 7 1 0 5 1".
The first guy returns and the second proposes a bet to prove his
point, that most people do know something about basic engineering. He says he will ask the blonde waitress a question, and the first laughingly agrees.
The second man calls over the waitress and asks "There are two stations on the tower you can see right outside the restaurant. One is on 101.5, the other is on 103.3. What are the frequencies of the third order intermodulation products?"
The waitress says "99.7 and 105.1" and while walking away, turns back and snaps, over her shoulder "And the fifth order intermod products are on 97.9 and 106.9"!
