If the title's accurate, there should be a pretty good blaze going at the Trap Door on Friday nights. This amiably awful sketch-comedy revue certainly supplies enough stupid: the frat-boy stupidity of the skit about an all-male cheerleading squad, the inscrutable stupidity of one set at a murder trial, the thin-stretched stupidity of another in which People Against Pro-Action carries out a guerrilla operation, the homage-to-Mike Myers stupidity of a fourth involving the lyrics to Queen's "Bohemian Rhapsody" ("Scaramouch, Scaramouch, will you do the fandango?"). And so on, through each of what you might call the 22 Stupidities. It helps that all this is lovingly, even sweetly offered, and that Erin Pallesen's so light on his feet for such a big guy. But the show's just terrible. The overall impression is of something brainstormed between turns at the PlayStation. Through 5/27: Fri 11 PM. Trap Door Theatre, 1655 W. Cortland, 773-384-0494. $10.
