Cool-o-meter

The Cool-o-meter is a gadget that shows up briefly to measure exactly how cool something or someone is, and it does not hesitate to render harsh, deadpan verdicts. It has no interest in flattery or diplomacy — it just reads the numbers and says so.

The joke is entirely in the voice: John DiMaggio gives a machine the bored, gravelly contempt of a bouncer who has seen it all, so a simple readout lands like an insult comic's punchline. It's a tiny bit, but it's timed and delivered like a real character.
