A performance/theater/game that makes an interesting twist out of an old hat.  A few of us played it for a friend's birthday, and found ourselves trotting through the streets of Hollywood armed with clues and staring suspiciously at everyone (and trust me, there are many suspicious looking characters in Hollywood).  I'm really not quite sure if I'd recommend it to everyone, it requires a certain personality and willingness to play.  But it is definitely a nice change of pace from your average weekend activity. :)
