Autobahn is a cycle of five short plays by Neil LaBute—the world's leading misanthrope—all of which happen in cars. In one, a jackass husband begrudgingly apologizes to his silent, weeping wife: "I was wrong. Is that what you want to hear? Is it? 'Kay. It was bad of me to call you a cunt, whether we were in the Albertsons or not." Re-bar is an appropriately moody place to watch a couple returning a foster child, a date turning sour, and other stripped-down vignettes on human awfulness. (Re-bar, 1114 Howell St, 233-9873. 7:30 pm, $15, 21+.)
