Along with Harry Shearer (and Kelsey Grammar), Hank Azaria is one of the few Simpsons voice actors you'd be able to pick out of a police lineup, thanks to his screen acting career and standup comedy. Azaria was on Conan a few days ago, and host Conan O'Brien (a former Simpsons writer) reminded Azaria that in his live performances he often draws loud boos from the audience when he announces that he won't be doing any Simpsons voices.
It's always a pledge he plans to break, Azaraia said, and when O'Brien asked, he said his most popular voice is Chief Wiggum singing "Let It Go" from Disney's Frozen. Sadly, Azaria only treated the Conan audience to a small sample of the song. But if you close your eyes, you can imagine the scene. Next, maybe he'll try Moe Szyslak belting "Can You Feel the Love Tonight," or Apu covering "Be Our Guest," or perhaps Comic Book Guy super-enunciating "Super-cali-fragil-istic-exp-iali-docious"? --Peter Weber
