We at Knife Depot have always promoted knife safety, so let’s get this disclaimer out of the way: Do not try any of this at home.

With that out of the way, it’s time to move on to a serious topic: battle bots!

Two of my favorite shows growing up were Robot Wars and BattleBots because nothing beats seeing two robots strapped to the teeth with weapons battle to the death. (Though ironically, my favorite battling bot had no knives and was called Blendo, which was created by the two guys behind Mythbusters.)

The folks over at the production company Rooster Teeth, which has more than 7.5 million subscribers on YouTube, created a Happy Hour series that follows the drunken journey of three people. In the first episode, they drunkenly thought of the idea to strap knives to two Roombas and let them battle.

They’re not the first people to turn Roombas into vehicles of destruction, but the video is worth a watch because it’s oddly satisfying.
