Charlotte Comedy Theater’s founder, Keli Semelsberger, studied with Amy Poehler and other luminaries of laughter in Chicago before bringing the exhilaration of living in the moment and the freedom of play to Charlotte stages. Sunday evenings let the company’s tightly wound japery unspool in two different directions. At 5 p.m., families convene for almost-squeaky-clean takes on traditional improv templates. Then, at 7 p.m., signature creation “The Gallery” plunks adult audiences down in a unique time and place, where performers spend the entire evening building a unified storyline from scratch and trying to ignore the bartender’s ceaseless suggestions of “whoopee cushion.”

Friday’s highly interactive short-form show is tailor-made to the party-ready atmosphere of the back room of Wet Willie’s, where servers deposit frozen daiquiris and other elixirs (not included with this deal) at table seating.
