The happiest rabbit expression is commonly called a "binky." It's impossible to mistake for anything else, and the first time you see one you will probably wonder if the poor thing is having a convulsion. When a rabbit binkies, it jumps into the air and twists its head and body in opposite directions (sometimes twice) before falling back to the ground. This can be done while standing in one place, or while running, which is really weird looking, and is sometimes called the "happy bunny dance." A rabbit can even turn 180o in midair. All this is a rabbit's way of telling you straight out that it is happy and overall pleased with you and its life. Some rabbits binky a lot and some hardly at all, even if they are being treated well. Everyone has their own temperment. http://language.rabbitspeak.com/rabbittalk_binkies.html
Eat Your Vegetables = this is good for you so set aside your violent metal persona for a few seconds to appreciate it. It's OK, the official voice of the forces of evil has told you it's just fine so you'll be OK. Hail Satan.
