If you think about Lady Macbeth’s famous cry and turn it around in your head for a while, “Out, damned spot!” just might lead you to a laundromat. That’s where playwright David Parmelee, of Shavertown, has placed Rachel and Sam, two actors with small roles in the Scottish play who steal away from a theater to wash some clothes — and maybe get to know each other better, and maybe start to channel some of the major “Macbeth” roles — in the laundromat next door. “We have actors (Becky Bennett Coursen, of Shavertown, and Dave Giordano, of Exeter) playing actors (Rachel and Sam) finding the lines from Shakespeare really serve their purpose,” Parmelee said. “Spots-Be-Gone” is one of two short plays, each with a “Macbeth” connection, that Parmelee has written and is directing for the Scranton Fringe Festival, which takes place Sept.
