Assange Guesting on Simpsons WikiLeaks founder appears in 500th episode By Rob Quinn, Newser Staff Posted Jan 31, 2012 2:49 AM CST 3 comments Comments Homer, meet Julian. (Fox) (Newser) – Homer Simpson shouldn't bother trying to keep any secrets from his new neighbor: Julian Assange. The WikiLeaks founder guest stars as himself in the Simpsons 500th episode, which will air Feb. 19. Assange recorded his part last summer while under house arrest in Britain, executive producer Al Jean tells Entertainment Weekly. In the episode, the Simpsons leave Springfield for a rugged area where Assange is the new Ned Flanders—in so far as "he lives next door,” Jean says. "The similarities end there. He invites them over for a home movie, and it’s an Afghan wedding being bombed." Jean says the 500th episode will feature plenty of other, less controversial cameos. Assange—who plans to start hosting a talk show in March—appears before Britain's Supreme Court for an extradition hearing tomorrow.
