Bear with me, my faves are: Something Smells, Shanghaied, The Secret Box, Band Geeks, Club Spongebob, Idiot Box, As Seen on TV, Krab Borg, Wet Painters, Chocolate with Nuts, I Had an Accident, and The Camping Episode. Like, I reference those episodes in regular speech like every few days.
When they get lost with the magic conch shell, when they sell chocolates, when Mr. Krabs opens up a hotel, when Spongebob and Squidward fight for employee of the month, when Spongebob gets too old for his grandma, when Pearl starts working at the Krusty Krab, when Squidward tries a Krabby Patty for the first time
One of our band directors was trying to give us a serious speech and said hoopla unironically. Someone yelled hoopla back and the whole band just fell out laughing. Our director was not very pleased.
