Glitches

The Legend of Zelda: Ocarina of Time
One famous glitch is the infinite sword glitch, look it up online for more details. This glitch makes your sword active, even though you're not swinging it around. You can walk close to a Gossip Stone, and it will spark up like it would have as if you were actually hitting it. This glitch is also effective on regular enemies. However, you can't jump off cliffs, and if you swing and attack regularly, you lose your ability to use the glitch, and have to repeat the steps of the glitch in order to use it again. There are also glitches that are involuntary, as in you didn't do anything to make it happen. Unless you use too many cheats like when your an adult in Ocarina of Time. The physics engine may be corrupted temporarily, and if you pick up a rock and throw it, it may float away and never return. Some glitches may be hazardous to your game, and do things such as freezing your game, or corrupting save files.

Another famous glitch is the swordless Link glitch that enables link to put the master sword away and have a blank B button. This glitch is done while saving after getting the sword knocked out of your hands by gannon at the final battle. Swordless Link opens a whole new world of glitches into the mix such as using any C button item while on Epona. This method of getting the glitch was fixed in V. 1.1 and all other versions after, But it is still possible to get the glitch using another glitch method known as ocarina items.

Wind Waker
The only glitch reported yet is an item glitch. To do it, set a rare item to X, Y or Z. Any item that is consumable will work. Other items will work, but doing it with the Wind Waker is tricky. Use the item and delve into the inventory simultaneously. Replace the item you are in the midst of using with any item you have. Exit the inventory. You will use the replaced item, with all of its effects active, yet if it is consumable the game will not deduce the number of items you have. This is because the game finished using said item after the replacement. It no longer remembers how many of the item is present, it adds one more to the quantity it actually has. In the case of bottling something with this glitch, it subtracts the quantity down to -1, deleting the bottled object. Consuming something in a bottle doesn't subtract, it adds 1 to the quantity like all consuming. A note: It only subtracts the quantity of the bottle if you bottled it yourself. It doesn't work when you sell Beedle something, the second item tries to be sold rather than the first. Also, this glitch can only swap once. It is perfectly safe to do this glitch. All credit to finding the glitch first can be placed in the form of a comment or guestbook signature here, as I, EmperorEmpoleon2, am the first to add this glitch to the Glitches article of the site. I may have very well been the first to find it. Maybe using it with first-person weapons may lead to other glitches. Also, a variation of the glitch using the Tingle Tuner may allow you to use weapons indoors. Video shown here. 

Twilight Princess
Twilight Princess has a large number of fantastic glitches that can aid you in multiple instances. There are certain glitches that are very humorous, and should be tried whenever you get the chance.

Cannon Room Glitch
This glitch was addressed directly by Nintendo, and plagues many of the launch versions of Twilight Princess. While Link is in the Cannon room in Kakariko Village, the player may be unable to exit the room if he or she saves the game while inside, turns off his or her Wii, and turns it back on again. Shad, who was previously in the room, will no longer appear there, however when the player attempts to warp the cannon, Midna will act as though a person is still in the room - however, Shad is nowhere in sight. When Link attempts to leave the room, Shad appears on a separate dialog screen, and asks Link where he is going. This makes it impossible for Link to leave the room by any means, as Midna won't allow him to warp and Shad will not allow him to leave the room.

Nintendo has stated that it will exchange the games for an updated version that does not have the glitch.

Arbiter's Grounds
Outside of the Arbiter's Grounds are two ledges with torches above them. At a certain angle, Link can climb up onto these ledges. If Link moves forward, or in any direction besides backwards, the "Falling" sound will be heard, and it will start you back at the entrance point with deducted health as if you fell down a hole.
