"The Simpsons Becomes TV's Longest-Running Primetime Scripted Series, Rubs It in Gunsmoke's Face - Watch "

With the airing of Sunday's 636th episode (Fox, 8/7c), The Simpsons officially becomes television's longest-running primetime scripted series. But Gunsmoke, which ran for 635 episodes from 1955 to 1975, isn't about to give up its title so easily. Fox on Friday released a special congratulatory video in which Gunsmoke's Marshal Matt Dillon challenges Maggie to a duel  which just goes to show how little of The Simpsons he's seen. After all, I wouldn't want to face off against Maggie, the baby that nearly killed Mr. Burns with a single bullet all those years ago. Following their little showdown, the video launches into a full-blown Gunsmoke parody, with each member of the Simpson clan spouting their infamous catchphrases. (You might second-guess Lisa's, but it's accurate.) 

^29 years and 635 episodes. I remember having to watch it on a small TV in the kitchen when it first came out and now it is on almost every day. I've also seen it in dozens of languages in most of the countries I have visited. ^
