Robert, another engineer at work, was telling me about his audio system (which he's forever modifying with assorted spare electronic parts). He looked at me seriously and asked:
Robert: Bob, why does an ungrounded audio amplifier hum?
Bob: Well, without a solid common ground for all the circuitry, you get sneak circuits, or ground loops, and ...
Robert: Nah! That's not it.
Bob: Okay, smart-ass -- you tell me, "Why does an ungrounded audio amplifier hum?"
Robert: 'Cuz it doesn't know the words.

You engineers are so funny.
