2. Stephen Colbert
Colbert is so well known for his political humor that his chops as a pure comedian are often overlooked. But he's one of comedy's quickest wits, not to mention an old fashioned physical comedian – a world-class mugger and slapstick artist, donning ridiculous outfits and wolfing down dubious foodstuffs on Colbert Report sketches. As for politics: He sets himself apart not just as a satirist, but as an activist, breaking the fourth wall with ingenious conceptual art stunts – testifying before congress about his brief tenure as a migrant worker, founding his own Super PAC to expose post-Citizens United money-swamped political campaigns, and in his most celebrated coup de theatre, spit-roasting President Bush, and the complacent press corps, in his appearance at the White House Correspondents Dinner in 2006.
