Doh is the catchphrase of Homer Simpson in the long running animated series The Simpsons, voiced by Dan Castellaneta since the show began in 1989. Written in scripts as an annoyed grunt, the short cry became one of television's most recognised sound bites and was added to the Oxford English Dictionary in 2001. Clips isolating and repeating it spread online through meme edits and soundboards, where a run like thirty two in a row turns a familiar reaction into an absurd, escalating joke about constant failure.
