Watchmen Easter Egg - Another 300 Reference

Toward the end of the movie, when it shows the streets right before the "disaster" happens, it shows people from looking on at whats about to happen. Malcolm Long, the psychiatrist from prison, looks up as his briefcase opens and all of the ink blot tests fly out. If you look closely at the lock combination, it is 300, a reference to Zack Snyder's earlier movie. Just another little clever easter egg.
