Did you know? Kramer’s legendary sliding entrance in Seinfeld wasn’t part of the script. During Season 1, Episode 3 (“The Robbery”), Michael Richards was late on his cue and burst into Jerry’s apartment so fast that he almost wiped out. Instead of stopping, he stayed in character, and the studio audience erupted in laughter. That unplanned moment was such a hit that it became Kramer’s signature move for the rest of the series. #seinfeld #tvshow #history #funfacts #movieclips | Historical Photos
