I know it's passe to talk about Majora's Mask glitches because of all the creepypasta shit, but on my first real playthrough of it, I got to the Spring Water Cave where Sharp resides, and right after he starts his song that hurts you until you die, I shit you not, the game completely froze with a sustained EEEEEEEEEEEEEEEEEE noise. Obviously it scared the shit out of me, though soon after the realization set in that this meant I'd have to reset, and since I hadn't saved in a while, I'd have to do a bunch of shit all over again, which turned fear into frustration.
