The sound comes from SpongeBob SquarePants, where Squidward treats free form jazz as serious art while everyone else hears a mess. Clips of the solo spread on YouTube and soundboards in the 2010s as a reaction to bad improv and fake-deep creativity. It remains popular alongside other SpongeBob staples like the spongebob sad song for opposite moods and the My leg gag for physical comedy, because all three are instantly recognisable even without the episode context.
