The last time I sat down to get through Ocarina of Time, around five years ago, it took me days. And that's with hindsight, and GameFAQs, backing me up.
An exploit has recently been discovered, though, which lets you beat the thing in under 25 minutes.
You can see it in video above, in which the player goes from beginning the end credits in 25:32, but since the exploit has hit the streets that time has already been whittled down to under 24 minutes.
Here's how it works:
The warp glitch reportedly allows the player to teleport from "Deku to Ganon's Castle escape", which means bypassing "adult, light medallion, magic, lullaby, and pretty much everything else". The result is a child version of Link running around with an adult Zelda, which I dare say will give your filthy, filthy minds plenty of fodder for the next few weeks.
