Cleveland Brown first appeared in Family Guy in 1999 as Peter Griffin's calm neighbor in Quahog, later headlining The Cleveland Show from 2009 to 2013. His panicked no no no became a running gag, most famously during scenes where his house is damaged and he slides out in his bathtub, helpless to stop it. Clips and GIFs of that moment spread widely online, and the audio was separated as a standalone reaction. It remains popular because the line is instantly recognizable without any visual context needed.
