Josie's Cabaret, the performance heart of the Castro, inaugurates Gay Pride Month with double doses of camp and scandal. A cast of strangely familiar characters -- cross-dressing baby dykes, zealous PFLAG moms, gay socialites -- populates the Half Baked Players' The Duboce Triangle: A Gay Soap, But Isn't That Redundant? The tawdry tale was written round-robin style in just two weeks, with four playwrights each creating a complete one-act play with ongoing plot lines and characters. It begins with Garret Groenveld's "The Menacing Phantom" and continues with installments by Theater Rhino's Dean Backus, The Theory of Everything author Prince Gomolvilas, and comedian Doug Holsclaw. The Hot Pants Homo Players, meanwhile, parody pulp novels in their sequel to Hot Pants Homo, Senator Swish. Imagine Jack Webb playing Oscar Wilde, the Players say, and you get a sense of what goes on, although you could just as easily imagine the Michael Huffington story with more exclamation points. Swish (with the teaser "He won the gay vote by a sinslide!") is about a candidate whose back-room doings undo his political career and his impending marriage. Both shows open Tuesday: Duboce begins at 8 p.m., followed by Swish at 9:30 p.m. (and both run Tuesdays and Wednesdays through June 23), at Josie's Cabaret & Juice Joint, 3583 16th St. (at Market), S.F. Admission is $10 per show; call 861-7933. For a complete list of Gay Pride events, check next week's Gay Pride Month calendar.
