Never watch the anime called *Boku*.

Yooooo!!! This guy received an animation sent by a friend, called "Boku" (Don't Cry?), he thought it was some kind of AV or something. He thought it wouldn't be a big deal to take a look, but after he finished watching it, he cried! That feeling is just like selling your soul to Lucifer, but you still can't help yourself and have to finish watching it!! And after you finish, you will shout Yooooooooooooo!
