"That's what she said" became a mainstream catchphrase through the US version of The Office, where Steve Carell's Michael Scott used it as his signature joke from 2005 onward; the phrase itself predates the show, appearing in 1990s comedy such as Wayne's World. As the series grew into a streaming-era staple, the line became one of television's most quoted gags and a go-to reaction sound for innuendo. The stretched "saaaaaid" variant exaggerates the delivery, and creators still reach for it whenever a sentence accidentally sounds suggestive.
