If Show and Tell was as much fun as Found Objects, nobody would have left preschool. For the skilled improvisers take the concept behind the familiar classroom activity and expand it into something exciting and altogether unpredictable. Each week, the performers will bring in an actual object from their day or request one from the audience. Then, with the audience’s support, they will craft a story on the spot that explores each object. As crowd suggestions and on-stage epiphanies build into a narrative, expect to be surprised and delighted by the hidden lives of everyday objects — and those that own them — during Found Objects at Unexpected Productions’ Market Theater. Friday and Saturday nights.
