in the cryo lab in MZ, at the tubes where you press a button, the "pod" inside the tube gets frozen and a new one takes its place.
well, i activated it and accidentially ran into the smoke thats around it whilst the pod gets frozen. my character goes stiff, locked in the running pose and falls to the ground and then gets up again after a second. major WTF moment for me, also one of the funniest moments ive had in the entire game
i got two more
once in a metro station (cant remember which) i decided to sleep on one of the 3 beds there. when i woke up i found 3 raiders sleeping in them, and one of them was in the same bed as me O_o
and finally, the stretch and spazz glitch. sniped a raider and she started flailing all over the place O_o
