8. Professor Frink
Professor Frink, Professor Frink, he’ll make you laugh, he’ll make you think.
Named for one of the writers of the show, Professor John Frink boasted the above when trying to cram himself in to '22 Short Films About Springfield', however the former is certainly far truer than the latter.
His inventions may have been ridiculously futuristic, but they were always funnier than anything. From Sour Candy 77X42, to the auto dialer that Homer used in his telemarketing scam, and of course the Monsterometer and the Frog Exaggerator, his inventions are rarely actually useful, but are always worth a laugh. He even managed to be the cause of turning Bart into The Fly when he sold his matter transporters to Homer for a few cents.
He first appeared in The Simpsons in ‘Old Money’, trying to procure money from Grampa Simpson for a Death Ray. However, he went on to be less of an evil scientist, and more of the painfully nerdy variety who didn’t like Mel Gibson’s new movie due to a lack of flubber (glavin).
Of all the Professor’s trademarks, it is his wacky voice courtesy of Hank Azaria that helps make him as popular as he is. Based on Jerry Lewis’ Julius Kelp from The Nutty Professor, Professor Frink could say just about anything in his voice and it would be funny.
