This is a local news report from ABC 7 in Denver starring a group of middle aged bicyclists and moped riders duking it out on a street corner outside Cheesman Park, allegedly after initially getting into a verbal confrontation about who had the right-of-way at a stop sign. That's easy, whoever got there first. Although, based on the scene, this looks more like the bicyclists might have felt they were being bottlenecked to the curb by the moped riders and took issue with that. No word who considers themselves the winner of the fight, but I give it to the guy on the far right who looks like he's having trouble standing because his penis is so big.
Keep going for the video.
