34. Michael Ian Black
The persistence of folks from MTV's Nineties sketch show The State is one of the nicer bonuses of the 21st century. Former Stater Michael Ian Black – whose sly, vaguely douchey on-stage persona apparently translates quite well to other media – has taken to that other recent phenom, Twitter, like the proverbial lobster to melted butter, weighing in on such issues as Lance Armstrong: ("If Oprah's smart, she'll have James Frey come out and give Lance a hug"), the President ("³Did anybody else notice a disturbing lack of Mummenschanz at the Inauguration?") and near-Zen koans ("Somewhere out there, somebody is excited about starting clarinet lessons soon.") Now can we get a feed from LeVon and Barry?
