In Uncharted, I can't remember the chapter, but I was in some cave where I had to pull on a chain to open up a door/exit (bit where you're with sully and you discover what "El dorado" itself actually is).
After the initial button pressing which initiated the pulling of the chain, when the chain started rolling by itself, I thought it'd be interesting to see what would happen if I jumped into it (to see if I'd get a reaction at all).
Well I jumped into it, then Nate got stuck in an infinite loop of his "falling down a cliff" animation. After about 20 seconds when the game realised he hadn't "hit/land" on anything it just went straight to the faded out grey death screen, with Nate still flailing his arms like he was falling.
