From 7 Totally Awesome and Totally True Ways People Quit Their Jobs:
While a writer for “Saturday Night Live” in the mid-1980s, comedian Larry David continually found his sketches on the chopping block. Fed up with his lack of input, David launched into a foul-mouthed tirade aimed at the show’s producer, Dick Ebersol, resigning in disgust ten minutes before airtime. While that in itself is a pretty impressive resignation, what came next is the stuff of comedy legend.
After spending the weekend lamenting his hasty decision, David returned to work on Monday as if nothing had happened. While his fellow writers were confused as to what he was doing there, Ebersol let David off the hook, and he kept his job. The incident later became the basis for an episode of Seinfeld.
