Homer Simpson is the central father figure in The Simpsons, the animated sitcom created by Matt Groening that began in 1989 and is voiced by Dan Castellaneta. Homer's exaggerated expressions of shock, joy and panic have been clipped for decades as fans shared favourite lines online, first in forums and later on soundboards and short video apps. This oh my god moment, tagged to a free trampoline scene in the show, survives because Homer's delivery is instantly recognisable, even without the picture, making it a reusable shorthand for disbelief.
