Hall of Infinite Doors

You are in a prison cell. You are wearing orange pants and an orange shirt and feel as if you could use a good shave. The cell is small and very simple, containing a bed that is basically a board with sheets, a toilet, a roll of toilet paper, and a barred window. You have no cell mates and can see through the bars a long hallway with many cells branching off of it. A single guard patrols the hallway. What do you wish to do?

NOTE: You have a switch blade.
