Cool-O-Meter

The Cool-O-Meter is an invention by Professor Farnsworth to detect how cool someone is. If someone is completely cool a thumbs up comes out and says 'oh yeah'. Zoidberg is not cool in any way, most people are half cool and Dwight, Cubert and Tinny Tim are completely cool when they imitate Bender. Coolness is measured in "Mega Fonzies."

Trivia

 * Mega Fonzies are a reference to the coolest character on Happy Days.
 * Cool-O-meter is a pun on Coulombmeter.
 * It is a robot because it appears on the "Wheel of Robots" in "The Devil's Hands Are Idle Playthings". However the Cool-O-Meter has only one hand to switch with Fry (though this could be a way on how the Robot Devil could have cheated Fry if the name was chosen)
