An invention created by Professor Farnsworth to detect the level of "cool" of any given person as measured in "megafonzies".
When it detects around 40 megafonzies, a gloved hand will pop out and give a 'thumbs up' and the Cool-O-Meter will say, "oh, yeah!".
When the device registers 2 megafonzies
, the user (let's just call him Russ), will not be able to attract guests to his subsequent party.
