Ros and Guil Number 2

This section starts with the two guys talking to the queen about seeing Hamlet, but then everybody leaves, leaving Ros and Guil alone. Of course since they are alone, they have to start talking about philosophy and things of that nature. Next they play this language game similar to a whose line is it anyway game. They have to talk in questions instead of just normal talking. I don't know what the signifigance of this is, but maybe it is showing that they don't know anything and are just lowly guards. Or, maybe I am overanalyzing this.
