goose
The late, great comedian Mitch Hedberg once said that ducks' opinions of him depended on whether or not he had bread. Well, we know one duck who thinks anyone with bread is TOTALLY AWESOME and he's got a little duck dance to prove it. If there were a duck version of Michael Flatley, Lord of the Dance, it would be this duck.

Except that this isn't a duck, as many, many, many commenters in a popular Reddit thread just pointed out. It's a goose. In fact, it's probably a bar-headed goose. The quibbling Redditors also proposed a lot of theories about why the duck dances, everything from Pavlovian conditioning to natural foraging behavior. My favorite explanation: it's used to paddling away after grabbing food, so the dance is just a form of land-paddling.

Duck, duck, goose ... whatever this bird is, it can sure as heck dance. I would be shocked if we don't see some duck remixes popping up very, very soon.
UPDATE: I was right! We did get a goose remix, from one of our biggest fans. Thanks, Colette! Keep these coming, you guys ...
