Don’t get me wrong, the winter Olympics is fun and all, but isn’t it just a little bit small-minded to limit ourselves to human competitors? Here are some videos illustrating how great this athletic competition could be if we made it just a bit more inclusive (and added some new events):
Event: Team Vertical Iceberg Jump. Competitor: penguin

Most animals live solitary lives, interacting with their own kind only to mate, raise young, or fight. In contrast are group-living animals, from meerkats to humans to Greylag Geese. Their sociality means an easier time locating mates and spotting predators, but it can also mean more disease and competition for resources. This competition can lead to injury and stress.

Breeding King Penguins crowd onto shores in huge numbers and claim tiny territories – about one-half of a square meter – where they incubate their egg and then brood the resulting chick. They have to defend these territories constantly, on average 100 times per hour. This occurs over a tiny space, since the penguins have an egg or chick on their feet and so can’t move much; most aggressive interactions are with neighbors no more than 50 cm away. Stressful interactions may not sound like a big deal – hey, we’re all stressed, right? – but these penguins are trying to maintain a high body temperature in cold conditions and keep their baby warm, and while doing that, they fast for weeks. They do not have energy to waste on stress.
