If you're looking for something to do this weekend, be sure to check out "Groundhog Hour" at the Greene Street Theater. Inspired by the classic Bill Murray film Groundhog Day, David Smith explores the repetition of a performer's life. With anecdotes and routines from his years as a juggler and circus performer, Dave shares what he has learned from doing the same 60-minute show over and over again. This show is part of the Philly Fringe Festival and promises to be very entertaining. Show times are Friday-Sunday, 9/3-9/5 at 8:00 PM, with an additional matinee Sunday 9/5 at 3:00 PM. Tickets are $15 and  are available at http://www.pafringe.com/details.cfm?id=13689.
