And now for an exciting bit of pop culture trivia: Spotted by our friends The Daily What, in this interview for the Archive of American Television, Dan Castellaneta, better known to you as the voice of Homer Simpson, explains how his character’s legendary catchphrase was born. As it turns out “d’oh” — written in the script simply as “annoyed grunt” — was inspired by Jimmy Finlayson from the Laurel and Hardy movies, but was shortened from “d’ooooooh” because Matt Groening thought it made for better pacing. Kind of incredible, right?
