Glitterati Productions presents Ken Ludwig's forgettable backstage comedy, notable only for being the vehicle that brought Carol Burnett back to Broadway in 1995. Concerned with a couple of aging hams and their struggling theater troupe, the play relies for most of its humor on tired stereotypes, tedious farce, and jokes way past their dates of expiration: "Grandma, can I get you your hearing aid?" "No, I don't want any lemonade." John Nasca's sepia-toned production has some nice 1950s period detail--the costumes, designed by the director, are especially fine. But the entire enterprise reeks of irrelevance. --Zac Thompson a Through 5/27: Thu-Fri 8 PM, Sat 6 and 9 PM, Sun 2 PM, Theatre Building Chicago, 1225 W. Belmont, 773-327-5252, $30-$35.
