Thank you, fourth wall, for protecting me from the thespians. Your mighty, invisible half nelson has pinned back many an actor from spilling forth across the stage’s threshold into a dark, dark place called cabaret. But I’m sorry, gentle friend; you have been scorned. The Renegade Theater Company administers a swift kick to the wall with “Comic Briefs Too: Four Plays for Coarse Actors.” The program, though disappointingly not about underpants, is a delightfully irreverent concoction of short works by Michael Green. Included are an a cappella opera, a mash-up of works by the Bard, and a murder mystery that tail-spins into chaos for want of remembered lines. Sound campy? Wanna poke a bit of fun? Too bad, suckers, they’ve beat you to the punch. Expect no respite from the hijinks between scenes, and keep a keen eye out for a charming if reluctant cameo by the lighting and sound engineer when the show starts at 2 p.m. (to May 8; see City List for other dates) at the H Street Playhouse, 1365 H St. NE. $15. (202) 396-2125. (Kara McPhillips)
