Journeyman movie and sitcom actor Jason Stuart has always had flair. He came out on Geraldo in 1993, and since then he's unabashedly celebrated flaming gayness in very funny stand-up routines. Like Jack in Will & Grace, Stuart's fond of jazz hands, snappy gestures, and "the f word" (fabulous); his energetic delivery complements a slick physical style. Sometimes he goes for the easy laugh (Cher, Cats), but usually he's lampooning gay stereotypes even as he's cataloging them. What makes him most effective as an entertainer, however, is his nimble mediation between gay and straight sensibilities--he treats neither as sacred. He's in town this weekend hosting "Laughing Out Loud," a comedy benefit for the Human Rights Campaign, a GLBT lobby. Also on the bill: Judy Tenuta and Alec Mapa. Fri-Sat 3/3-3/4, 8 PM, Park West, 322 W. Armitage, 773-929-5959 or 312-559-1212, $50.
