In 1972, National Lampoon expanded into recorded comedy with Radio Dinner. The album was largely a star turn for a young NatLamp contributor named Christopher Guest; when the magazine followed up on Radio Dinner's success by sponsoring an off-Broadway "satirical joke-rock mock-concert musical comedy semi-revue," he was tapped to perform in it alongside a drummer named Chevy Chase and a 24-year-old John Belushi. National Lampoon's Lemmings (original cast album) was another hit, running for 350 performances of Woodstock parody and Joe Cocker mockery. NatLamp editor Michael O'Donaghue decided the time was right to take the brand to a weekly radio show. He brought the stars of Lemmings back for it, together with Belushi's old Second City castmates Bill Murray, Gilda Radner, Harold Ramis, Joe Flaherty, and Brian Doyle-Murray. Harry Shearer, Doug Kenney, and Richard Belzer helped round out the cast of The National Lampoon Radio Hour.

"None suspect that idealistic committed little folk-singer Bob Dylan is in fact the amazing Zimmerman -- faster than a proxy ballot, more powerful than an ulterior motive, and able to buy tall buildings with a single bond!" [More inside]
"A Brief Survey of the Various Foreigners, Their Chief Characteristics, Customs, and Manners." Israelis, "They were personally responsible for the fall of the Roman Empire, the 1929 stock market crash, and the loss of World War II by a prominent European country." On Canada, "It is thought to resemble a sort of arctic Nebraska." It's okay because it's both unapologetic and National Lampoon circa Animal House. Harvard boys in the 60s were original ironic hipsters!

First National Lampoon does a "parody" of the bumps on Cartoon Network's popular Adult Swim programming block. Then G4's Attack of the Show responded (and the editor of the Lampoon's site responds in the comments -- look for posts by JayPink), and then Adult Swim themselves did on Sunday (Flash re-creation of the aired bump).
