LyonEvents posted a video of Les Cartonnades, or The French Box Wars, at Japan Touch Haru, a geek convention held in Lyons, France. Qu'est ce que Les Cartonnades? A group of grown men forge armor and weapons out of cardboard and then battle to the death ('til their cardboard armor has been destroyed). They have done this fifteen times.
Turns out, an axe with a dragon-shaped blade is still the best weapon, even if it's made from the box that Amazon sent your Gilmore Girls Season 4 boxset in.
