This long-running show at Boston's Charles Playhouse combines music, comedy, and multimedia. These guys may not say much (OK, they don't say anything) but they certainly know how to entertain. Student rush tickets to see the Blue Man Group can be purchased one hour before a performance, based on availability, for $39 each.
