Post the chaos theory moment that made you laugh the hardest, to get you started I'll post my favourite memory whilst playing this game.

It was the bathhouse level I believe, in the area where there is a large dry pool with varius working tools inside.
Anyway, I alerted one of the guards, by not getting passed a jammed light fast enough, and proceeded to quickly shoot out all of the lights and hide behind a crate.
The guard called his buddy over, hopped down into the dry pool said something along the lines of "I swear it was here a moment ago", he was just about to walk off when his buddy jumped down, on top of him and knocked him out. I laughed so hard that I couldn't regain my control of the game and the guard saw me and killed me.

Ok, post yours
