Alan Partridge is the fictional Norwich broadcaster created by Steve Coogan and Armando Iannucci, first heard on the radio satire On the Hour in 1991 before fronting Knowing Me Knowing You with Alan Partridge in 1994 and I'm Alan Partridge from 1997. His triumphant 'Aha!' became the character's trademark, quoted by fans for decades and later clipped into short reaction sounds for memes and edits. Like You What and the Woody Woodpecker laugh, it endures because the voice alone carries the joke, needing no context to land.
