Lol, that guy shooting the arrow onto his own head reminds me of playing the Elder Scrolls games. I would do the same thing. Fire an arrow straight up (near a guard or other innocent person), and watch it slowly come down and clonk them on the head.
Some Americans might be guilty of the same thing and not know it. I sometimes see random people with Japanese Kanji Tattoos and I'm wondering if they know for sure what that s*** says.
