The problem with a "fest" of any kind is the quality-to-crap ratio, but the good folks at SketchFest have done the work for you, curating an evening of comedians who specialize in self-contradiction: All American Push Up Party (Dusty Warren, whose comedy grows from the tension between his grumpiness and his goofiness), Becky and Noelle (featuring Becky Poole, whose comedy grows from the tension between her peppy attitude and her macabre mind), and an NYC-based group called Sidecar (a mystery). Hosted by David Cope, the world's meanest, most sardonic harp player. (Annex Theatre, 1100 E Pike St, 800-838-3006. 8 pm, $15, all ages.)
