If good theater should do something that movies or television can't, then Fat Pig is fucking great theater. In Art-attack's tiny 40-seat space, the play happens right in your lap. And because Fat Pig is one of Neil LaBute's more uncomfortable plays—a skinny man dates a plus-sized woman until he realizes people are judging him for it—the discomfort level is incredibly high, in a good, thought-provoking way. But it's not just a shockfest: The script is sharp and the performances—especially Rachel Permann as the big, sexy librarian—are top-notch. (Artattack Theater, 1715 E Olive Way, 905-9835. 8 pm, $14–$25.)
