I found the above video onBoingBoinga few moments ago and while no one seems to know whether these kids are actually trying to harm each other, this is some pre-planned show, or if this is how Tetriminoes mate, in the end does it really matter?
Watching these two goofy bastards smash their crude cardboard geometric shapes together in an orgy of awkward pseudo-violence is reminiscent of the days of the Roman Colosseum, only everyone is pale as death and these kids probably smell worse than the nearby Vomitorium.
