Remember that video from earlier this year where an artsy, fartsy filmmaker asked 20 strangers to randomly make out? Since random acts of affection between strangers is only mildly interesting, someone one-upped him with random acts of (consensual) violence between strangers.
The Internet truly is Vishnu and Shiva. You just know that any video that starts off we “We asked 40 people to hit each other in the face for the first time” is going to be gold.
