Humans are a competitive bunch. We innately rally against each other in constant battles for supremacy, as you'll see in this cluster.

From the inspiring disabled Bodies in Motion modeling contest, to the very bizarre household item races and innovative skyscraper competition, there are no shortage of ways to compete in something.

Some competitions and contests serve a discrete function--designing a company's logo, for example, or helping to create a new soundtrack. Others, however, are more for laughs than relevance, like the Paris Hilton obituary contest for children.
