During the 21 years Theater Schmeater has lived in its subterranean theater-bunker on Capitol Hill, it has regularly produced part-campy, part-sincere re-creations of Twilight Zone episodes. People love them: the fascination with the outer edges of science, the moral queasiness about our workaday existence, the cheap cocktails. This round has entertaining shorts about marooned astronauts, a tyrannical and psychic child, and a drunk-ass Santa Claus. Schmeater will have to relocate soon (due to real-estate issues), so enjoy this old bunker while it lasts. (Theater Schmeater, 1500 Summit Ave, schmeater.org, 8 pm, $18 adv/$23 DOS, through June 15)
