As a great man once said, “Woo-hoo”, according to New York Times. On Thursday Fox said that it had renewed “The Simpsons” for two more seasons, confirming that the show would become the longest-running scripted prime-time TV series. That record has been held for more than three decades by “Gunsmoke,” a western that ended in 1975 after 20 years. The current season of “The Simpsons” tied “Gunsmoke,” and its 21st season will surpass it. Homer Simpson will keep inventing catchphrases through at least 2011, when the 22nd season will theoretically end. (The show is still young by Mr. Burns’s standards.) The NBC criminal drama “Law & Order,” in its 19th season, follows closely behind.
