The fabulously French Eugène Labiche was good at what he did — writing glittering vaudeville-style farces about the bumbling bourgeois. His most famous work is An Italian Straw Hat, but the folks at Company Onstage are taking on one of the writer’s lesser done comedies, The Threesome, adapted by Neil Bartlett.

The risqué tale about an adulterous middle-class couple takes place in Paris. It’s 1870, and all the romping wickedness of sex on the down-low during the Victorian Era is captured by the play’s wacky characters. There’s a suspicious maid who’s out in the kitchen making hay with the fireman; a pesky, blackmailing cabdriver who definitely knows much too much; and, of course, a naughty lover stuck in a drainpipe. 8 p.m. Fridays and Saturdays. Through June 11. 536 Westbury Square. For information, call 713-726-1219 or visit www.companyonstage.org. $15.

Fridays, Saturdays. Starts: May 6. Continues through June 11, 2011
