There is another great one in one of the Legend of Zelda games.

The game world is paused whenever Link pulls an item from a chest, but because his animation does not loop perfectly, because of a missing frame, he slowly slides across the ground and even through walls.

One of the minimum % speedrun abuses this by looping the animation for many hours in order to glitch through a wall, and not collect a progression item, which would count towards the collection percentages.
