You can not unknow what you will know by the end of the video (it involves large needles, scalpels, and emergency medical procedures on the penis. It isn't graphic but your imagination will fill in the blanks).

Also, trigger warning for spiders, especially the huge, long legged, alien-lookin' monster on the presenter's face at 0:33. There are other, less freaky spiders further on but that one's a special kind of hell beast so you might want to watch the start up to skip 0:33 then skip to 0:45.

I warned you.

edit: sorry the video thumbnail is a spider, too.
