[SPOILER] What was your stupidest/funniest moment that you did in Amnesia?

[grrrz]

after getting the chemical coumpound to open the padlock, I took the compound, took the stairs crouching, then the compound got stuck and fell in the space below the stairs that was unreachable. Since I didn't think I could load a previous save (can I?), I used a chair to climb on it and tried jumping and grabbing it very quickly, it took me like 50 tries to get it back.
