I liked the part early on in the litter-filled subway where the patrolman tipped over the bottle from the garbage can and said "Pick it up." If you resist he beats you up. If you do what he says you get to go about your business of eventually defeating the oppressors.
Being the troublemaker I am, I discovered that if you throw something at the patrols in the train station, they'll chase you down and beat you up for it - if you run, they eventually give up chasing you though ;)
