If it was enjoying itself, it'd have its whole neck extended, instead its head is retreated to avoid being smacked in the face. Poor beastie, I hope it bites the fingers off whoever did that.
I heard a rumor that the people who made this clip have been fined for animal cruelty. Also, they are being put on a giant roomba and getting their head smashed every time it hits a wall. And someone is putting the video on the net.
