Julian Assange to appear on 'The Simpsons' Homer and Marge meet their new neighbor Julian Assange (guest voice as himself) in "At Long Last Leave," the show's 500th episode, airing Feb. 19. "The Simpsons" is making some big headlines, and not just because its 500th episode is just around the corner. WikiLeaks founder Julian Assange is set to appear on the animated show's landmark episode on Feb. 19. EW.com reports that Assange -- who is still under house arrest -- recorded his lines for the guest spot over the summer from a location unknown to "The Simpsons" producers. "I was just given a number to call," executive producer Al Jean told EW of directing Assange remotely. That 500th episode, titled "At Long Last Leave," the Simpsons family are evicted from Springfield, according to Fox. It is in their rugged new community where they meet their new neighbor played by Assange, Jean told EW. "He invites them over for a home movie and it's an Afghan wedding being bombed," Jean revealed to the magazine. The WikiLeaks founder is accused of sexual assault on two of the website's volunteers. U.S. officials are also debating whether to bring any charges against him, possibly under the Espionage Act, for publishing U.S. diplomatic cables online. "The Simpsons" airs at 8 p.m. Sundays on Fox. What do you think of Assange guesting on "The Simpsons"?
