I like the growl that is administered to every video cat larger than a fat tabby. IF I ever hear that sound IRL, I won't be thinking cougar or bobcat, rather how to deter the jaguar from crushing my skull.
In this vein there's an amazing line from Man on The Moon when Kaufman refuses to let canned laughter be dubbed over his show: "That's dead people laughing! You know all those people they recorded are dead by now, right!?"
