When "Saturday Night Live" runs out of election fodder, its writers can turn to "Girls Only" for timeless, laugh-out-loud skits. Written by two Denver women, the show, about all things girlie (diaries to menopause), is so beloved its producers recently added two more performances to each week of its run. Through Dec. 21 Wed-Fri 7:30 p.m.; Sat 2 p.m., 7:30 p.m.; Sun 2 p.m., 7:30 p.m. Garner Galleria Theatre, 1101 13th St. $36. 303-893-4100, official website
