'That's what she said' became Michael Scott's recurring catchphrase in the American version of The Office, where Steve Carell's regional manager used it to turn everyday remarks into innuendo. The joke worked because Michael treated it as clever even when colleagues groaned, and that running gag made the line instantly recognisable far beyond the show. As clips circulated on social media and soundboards, the short delivery became a shorthand reaction for any accidental double meaning, which is why creators still reach for it to punctuate jokes, edits and chat replies.
