COMEDY: The Impatient Theatre Co. is having their weekly “Harold”-style improv performance tonight. “The Harold” refers to the comedic form created by Chicago improviser Del Close and boasts a more layered approach to long-form improvisational comedy (essentially, it’s a multi-scene comedic game that lasts around half an hour). Tonight, two teams face off in a comedic battle: trio Trompe Le Monde, and the all-female troupe WDWMKR (pronounced “widowmaker”). The Savannah Room (294 College Street), 8 p.m., $5.
