I think this might have been some sort of freaky glitch in the game: I was wandering the wastelands once, when I got attacked by a mole rat and a raider at the same time while on the side of hill near an overpass. I shot the mole rat dead, then shot the raider, and after the raider's dead body fell over the mole rat's dead body, he started levitating in the air spinning at incredible speed. When I went over to his floating body, as soon as I touched him, he stopped spinning and floating, but I was killed instantly and sent flying a long way, fliping around through the air during the whole flight until I finally went SPLAT! into a wall. It was f*ckin' hilarious.
