[Death by Mirrors]

During my most memorable session one guy ended up spending eternity in a very deep hoistway (he had a feat that would slow down his fall enough for him to survive and a magical item keeping him from starvation), two marched straight into a black hole they mistook for a portal, and another player lost all of his clothes. In hindsight I guess we deserved it, because our way to identify traps was to run them over with a mule called Bob and a dozen of his clones.
