This cartoon / music video from Japan was an easy pick for today's WTF Friday Clip. It was making the rounds on the interwebs this week, and is the perfect way to waste a couple of minutes while sitting at your desk waiting for the long weekend to kick off. Yes, this little ditty is about a bug that bites asses. Tight asses... hard asses... shriveled asses... they are all potential victims of the butt biting bug. In case you feel like biting a butt today, just be warned, as we are told that big city butts are bitter.
