What are the most interesting glitches you guys have had?

super mario 64

This happened

This is one of my favourites. The weird ribbon thing in the sky is actually a character model and when I had it on the Xbox 360 version it was so huge, twisty and weird it lagged the game.

Also from Bethesda :P Made even funnier by the fact it only happened after a patch that was supposed to make the game less buggy.

Did anybody watched this yet! It's awesome!

This I saw online, was pretty funny

Hmm, I remember falling through the floor in Daggerfall's dungeons a lot. :( Maybe it was interesting the first couple of times, I guess. :)

Idk if it was a glitch , playing Fallout: New Vegas and i arrive with an NCR guy who helped detach the death collar from me from the Brotherhood ,so we are at his base but he never continued to say how we were gonna ambush or report the brotherhood of steel at hidden valley , all he said was "yea yea tell me everything at the base" or something like that , so i check what he had on his table and there was a busted radio receiver so i try to fix it and it should have been fixed but it says i broke it , the NCR guy starts freaking out and shoots me , my companions just kill him , weird .

i feel like if i say "Ocarina of Time" that should sum it up pretty well.

The Skyrim Giant Space Agency glitch as I liked to call it. Hit by giant, turn into satellite (at least at low levels).

There are others, I'm just too lazy to go look for videos.

pokemon first game. You must be know what I mean.

So many I can't even remember all.
THIS & THIS.
In OMD some archers start flying while shooting orcs :D Got myself some cool air support.

Cracked.com has a few articles about this.

Falling through the world is also always fun. Yesterday I was playing Planetside 2 in a full Sunderer(Troop Transport) and as the driver was trying to navigate some rough terrain, we fell through the map and everyone died.

I've caused a couple myself. My favorite was probably in Psychonauts when I managed to completely eff up the rendering engine somehow, which made for some really interesting visuals:
Psychadelic Psychonauts

Then there's the good ol' fashioned fall-through-the-floor glitch (Borderlands 2 in this case):
Borderlands 2: A New Low

The guy in red is supposed to be a boss, but was acting like a player character. The little gesture is just his idle-player animation [intended to break the 4th wall].

My view used to desync from my actual position in Borderlands 2, so i had my arms floating around... :D

I don't have anything recorded that is recorded in video as a glitch, but I do have this although didn't publish it.

Crows trying to bring home a man

In Joint Ops after exiting a helicopter from the gunner seat I still had the minigun as a weapon and could run around with it. The weapon was invisible, but it worked.

And this stupid guard in Oblivion of course.

glitch of this key Z8XGC-V4WME-2HIFZ actually working :/

SHAUN!!!
one of the funniest glitches i know

lydia got tagged as a horse in skyrim somehow. went to talk to her saw the action "ride" instead. This was unexpected since in the past when I pointed her to a bed so I could steal some blood while she slept she misinterpreted and says "not for you not for anyone" I mean that button would make more sense on birna of winterhold but whatever.
so I clicked to ride and nothing happened though. :( was hoping it was like the red dead redemption horse glitch but no. then I clicked again the button went away and I slid a good distance and ended up on my horse way over there instead.

I had this happen

I think i have a new contender for one of the best glitches ive ever experienced

This was one of weirdest I saw. I also got weird glitch in metro 2033 that made 2 hunters.
