4. Band Geeks – season 2, episode 35b:
We are introduced to Squilliam Fancyson in Band Geeks, when Squidward makes the mistake of telling Squilliam that his band (to be made up of unknowing Bikini Bottom-ers) will be playing at the Bubble Bowl. This leads to an awesome compilation of almost every named character in the town – from Plankton to Larry the Lobster – getting in a joke or two, while banding together to help Squidward, much like in the future episode, Squilliam Returns.
Most of the gags in Band Geeks center around Squidward’s bleak existence, but it’s also stuffed with one-liners from and about each of the characters on the show, such as the line “These claws ain’t just for attractin’ mates!” from an about-to-brawl Mr. Krabs and when Squidward says, “No Patrick, mayonnaise is not an instrument,” in response to an inevitable query from the stupid star.
Lest we forget the heart-warming end of the episode, when Spongebob and the gang practice all night long to become an amazing band behind Squidward’s back, fulfilling his dreams and causing Squilliam Fancyson to faint at their Bubble Bowl performance of “Sweet Victory” by Buck Green.
