Michael Kelso, played by Ashton Kutcher, was the lovable, dim-witted jock on That '70s Show, the American sitcom set in Wisconsin in the 1970s that ran from 1998 to 2006. His exaggerated reactions became one of the show's most recognisable running jokes, and short clips of his voice later circulated on soundboards and social video as a quick way to flag a silly realisation. It endures because the tone is instantly familiar to sitcom fans and works without context, turning an ordinary mistake into a punchline.
