Best cheat-code,glitch,or easter egg in any game.

The cursing door in Fallout 3 was priceless.

The one that prevented you from using "search" properly.

I'll say it once, and I'll say it again: The Search button glitch.

Flying cars in GTA San Andreas were awesome.

The Red VS Blue guys in Halo 3

Bunnyhopping found in Quake 1. It was such a good bug that id Software adopted it and kept it within subsequent releases of the game (Quake 2 and Quake 3). It is now known as strafe jumping and is a slightly different technique.

 

[Pumpkin_Eater]

The D&D cinematic in Summoner.

 

[MURPHYCHACHO]

I'm offended no one's mentioned the UFO endings in the Silent Hill games yet!

Cheat Code: The Konami code of cource. It's the most famous. The codes in Vice city are pretty memorable to me as well, because if I act like I'm holding a PS2 controller, I can still do them by heart.

Glitch: I think my favorite glitch would be being able to get into a closed boxcar in GTA4. I never used it to get an unfair advantage...but the other team would be shooting at me to no avail and thinking...wtf?

Easter Egg: All the refrences to past games in both Final Fantasy IX and XII.
