I use to always in GTA 3, take an ambulance into the subway tunnel, wait for a train, stand on top of the ambulance and normally the force shot me through the roof into glitchy blue crazy land and then just teleport me somewhere random. Also, y'know that bit in Bioshock towards the beginning when you get the revolver, I listened to the splicer talking to the baby pram as though she were talking to a baby, I go up, take her down, look in the pram and it was a MOTHERFUCKING GUN SHE WAS MUSING TO! Also the clown in Dead Rising, need I say more. Also the rooms in P0rtal with all the photos of cake, and he musings of cake, and likewise with the companion cube.
