46. Daniel Kitson
David Cross called this Brit "the funniest comic I've ever seen in my life." Kitson – a cult figure averse to TV appearances, comedy albums and interviews – specializes in wringing brilliant comedy out of dark situations: A 2011 one-man show (which played a sold-out run in New York) was called The Interminable Suicide Of Gregory Church. Kitson's riffs are often perfectly crafted, but they're not always so heavy: In one stand-up clip on Youtube, he talks about his fascination with pigeons for several very funny minutes.
