I know this horse head mask is meant to be grossly unsettling to the viewer, but when I look at it all I can think of is Kramer Tourette's-ing out "Gggiiiddy up" and I feel more amused than disturbed. I imagine the expression selected for the mask represents the face horses make when they see a mouse, or fat person headed their direction fixin' to ride them.
The equine-flavored latex head sack has a realistic fur mane and, more impressively, 693 user-submitted photos accompanying its Amazon listing. That has to be some kind of record. Are startled horses really that funny, or is this an indication that predisposition to bestiality is a lot more mainstream than I thought?
