It seems like some people in the world have absolutely nothing better to do than meet up in weird underground tunnels and beat the crap out of each other. Sure, it’s not the way I wish that I could spend my Saturdays, but we’re glad that they do because we end up getting to see videos like this.

In the video below, two dudes are meeting up to trade blows in some weird sewer duct that looks like something out of Teenage Mutant Ninja Turtles. They blast each other a couple of times before one guy connects with an absolutely sweet spinning back fist that totally sends the other guy to sleep. That’s all she wrote:

Yeah, he isn’t getting up from that any time soon. I think my favourite part of this though is just how many people seem to be there watching this, like this is literally something they get involved with every week as a fun pastime. Go buy a video game or a skateboard or something guys.
