rake bit
n.— «“The Rake Bit”: Something that’s funny, goes on too long so it’s not funny, then goes on so long that it becomes INCREDIBLY funny. Goes under a couple different names, but of writers my age, this seems to be the most prevalent. Based on The Simpsons ep that was a Cape Fear riff. Sideshow Bob climbs out from under a car and steps on a rake. It smacks him. He mutters. He then steps three feet away …onto another rake. He mutters. ad-near-infinitum.» —“Writing: Jargon Preservation” by John Rogers Kung Fu Monkey Apr. 15, 2005. (source: Double-Tongued Dictionary)
