Jimmy, Jimmy and Jimmy

Jimmy A, Jimmy B and Jimmy the Ghost were a group of two humans and a ghoul who boarded in a seemingly abandoned vault, only to discover it was full of peaceful ghouls and members of the Brotherhood of Steel. Disappointed that there was nothing interesting in the vault, Jimmy A and Jimmy B casually slaughtered the inhabitants of the vault before turning on each other.

Jimmy A
Jimmy A was a loud-mouthed bigot with racist views about ghouls, considering them abominations. He was proficient at killing people both with his bare hands and with ranged weapons, though in close combat he was quite inept at making a straight shot with a Gravity Gun, and at one point pulled out a rocket launcher before being hit with a bathtub. Jimmy A ended up alone in the vault after killing everyone.

Jimmy B
Jimmy B was heavily into Jazz music and frequently talked about it, something that Jimmy A taunted him about. Jimmy B was a much quicker shot than Jimmy A and frequently beat him in fights. Jimmy B disappeared after hitting him with a bathtub.

Jimmy the Ghost
The quietest of the group, Jimmy the Ghost was apparently a childhood friend of Jimmy A. Jimmy the Ghost refused to partake in the slaughter of the inhabitants of Vault 196. He was murdered by Jimmy A, who shouted "Sit down, you look tired!"

Behind the scenes
The three Jimmy's appear only in Gmod FALLOUT 3 Mod! Jimmy A was played by Jordan Frye, Jimmy B by Isaac Frye, and Jimmy the Ghost by an NPC. The reason for Jimmy B's disappearance was Isaac was kicked from the game due to LUA errors.
