As someone who has spent the better part of 15 years reading and researching Billy the Kid history I can tell you that his Drunk History was surprisingly accurate considering it was told by a drunk dude on Comedy Central. I've seen shows on the History Channel that didn't even come close to being as factual. The native New Mexicans did love him, he had LOTS of girlfriends, and Joe Grant was a total asshole. (Side note: a few hours earlier Grant, being a bullying asshole, had stolen that pearl-handled gun from someone else in the bar and Billy, having a feeling that something bad was going to happen, did ask to see it and spun the barrel to an empty chamber. Later on, Grant started threatening the guy Billy was sitting with because he'd mistaken him for the guy's brother and when Billy tried to explain that he was mistaken, Grant called him a liar. Billy turned to ignore him, Grant fired his empty round at Billy's back and, hearing the *click*, Billy spun around and fired three shots into Grant's head.)
