If you’ve ever watched an episode of a sitcom, you’ve seen human watermark Fred Armisen in a guest role. That kind of acting range requires an equally adaptable voice set, so it should come as no surprise that Armisen told Conan O’Brien that he can do “any accent … any small part of a town, any big city, I can do it all.” Except — wait — that’s a bananas big claim. To test it out, O’Brien threw out regions that were completely, definitely, positively, for sure not rehearsed. Armisen seems to do pretty well, but of course, all great savants have their Achilles heel. The slippery foe that keeps Armisen up at night: Jamaica.
