What do you get when you bring together one of the Five Lesbian Brothers with one of the Split Britches? (Props to anyone who can come up with an awesome punch line to that riddle . . .) You get the theatrical equivalent of Ellen and Portia. Lisa Kron and Deb Margolin, both Obie winners for work in their respective companies, have teamed up for the first time in Time Is the Mercy of Eternity. Margolin’s play is composed of four shorts about love, violence, and obsession, including a bus driver’s frustration with suicide bombers; a couple’s loss of their son, a soldier in Iraq; and the murder of a young actress. In the title piece, Kron stars as a woman who won’t leave the home-furnishings section of a department store that she insists she owns.
