Easy Targets
I recently saw a play called Easy Targets in Los Angeles, in which the audience gets to throw provided rolled up socks at the solo actors at any given time. By the end of their performance, the stage was covered in multi-colored socks which had inspired this new drawing. It was quite an entertaining experience, especially when their trying to recite Shakespeare. (P.S. No offense against Shakespeare, I just thought it was fun to throw socks.)
