LOS ANGELES - A Good Samaritan who's been dubbed "The Viking Guy" swiftly taught an unruly and obnoxious L.A. train passenger a lesson.
The shirtless, impaired man appeared to be threatening other passengers, becoming angered when someone called him a "weirdo." One man was holding up his bicycle as a way of defending himself.
It appeared that a fight was going to break out between the man and another passenger, when Adrian Kaczmarek stepped in, seemingly from out of nowhere.
He quickly placed the 25-year-old man in a chokehold and after a few seconds, the man was on the floor unconscious.
"Daaaaamn, this is going viral," someone remarked in the background.
