The SpongeBob diapers meme, often referred to as 'Hmmmmm,' originates from the 2002 episode 'Rock-a-Bye Bivalve.' In the scene, SpongeBob and Patrick have adopted a baby scallop, but Patrick neglects his parental duties. To prove how much work he has been doing, a frustrated SpongeBob leads Patrick around the house, pointing out increasingly large and disgusting piles of dirty diapers hidden in various spots like the garbage can, the couch, and even the wallpaper. The meme is widely used on social media to present an overwhelming amount of evidence or examples that refute someone’s claim, with each panel representing a new piece of proof.
