A guy is looking to buy an expensive car, tests it out, and comes back to the dealer to complain, 'This is an expensive car, but the radio doesn't work.'
The dealer explains, 'No, no, this is a high-tech state of the art car radio. All you have to do is say what you want to hear. Say 'country music' and country music comes on. Say 'rock n' roll' and rock 'n roll comes on."
The guy says, "Great, I'll take it." The guy is driving it off the lot and turns into the street when another motorist cuts him off. "JerK!' he mutters—and Rush Limbaugh comes on.
