In an age where seemingly everyone stresses about how long their games are versus how much they cost, it seems like some people just can't plow through them fast enough. Take Cosmo Wright's insane run through The Legend of Zelda: Ocarina of Time, for example. Using glitches, he managed to clear the entire game in just 18 minutes and 10 seconds, setting a new world record. You can watch the whole thing in its entirety above, and you can do it in the span of your average lunch break.
Meanwhile, speedrunner T3 set a world record in another beloved Nintendo game, Metroid Prime. He sent Samus through the GameCube classic in just 55 minutes of in-game time. Check out T3's run after the break.
