''Stella" is the kind of sitcom that makes a reviewer want to throw up his hands and say, ''Oh, just watch it." And that's not because Comedy Central's ''Stella" is so amazingly wonderful, although it certainly is a fresh kick for viewers who like willfully offbeat shows such as ''Reno 911!" No, just watch it because it's so freaking odd, and so original, that it's really, really hard to describe.
In its promotional push, Comedy Central has been likening ''Stella" to the Marx Brothers, and there is truth in that lofty comparison. But the show, which premieres tonight at 10:30 p.m., is also built around an ironic sensibility that feels altogether contemporary and ''Mad TV"-esque. It follows the Manhattan adventures of three bumbling men in suits -- played by Michael Ian Black, Michael Showalter, and David Wain -- as they suck innocent bystanders into their web of modern surreality. Acting like big kids, they charm a co-op board by doing a zany dance, and they perform heart surgery on their landlord with a butter knife. In short, they're an interactive seminar in absurdity.
