Holy Guacamole. Those debates make me sad. Has everyone forgotten that t.v. shows are written by PEOPLE? More specifically, a STAFF of WRITERS? Isn't it just possible that out of 13 million Simpsons episodes there could be a one-off line that's not so hot, barely makes any sense, and maybe not entirely faithful to the 1100 year continuity of The Simpsons?
Maybe TRL is right. It could be "viral marketing". Or even a conspiracy to cover the tracks of lame jokes of years past. "We really dropped the ball on this Ralph/Viking/Sleep joke back in Season 58 of 1783. This new movie might uncover this past indiscretion. Best thing to do is actually to put it out there ourselves, but with a mole who himself is confused about the barely-understandable one-off line." It's like the Swiftboats thing or something.
Also, I gotta say, cheers to The Simpsons for striking while the iron has been dead cold for 4 years with this movie release.
