DECISIONS—The best late-night talk-show host on the air, The Late Late Show's Craig Ferguson is a hell of a stand-up comedian. And while he's known as the voice of Archer and Home Movies' Coach McGuirk, Jon Benjamin is also hilarious. Tonight they're both in town. Separately. This is like Sophie's Choice! But funnier. EH
Craig Ferguson at the Aladdin Theater, 3017 SE Milwaukie, 7 & 10 pm, $42.50-55; Jon Benjamin at the Bagdad Theater, 3702 SE Hawthorne, 9 pm, $15
