7. Chris Cooley
When you are the biggest joker on a team with Fred Smoot and Clinton Portis, that's saying something; and on the Redskins, Chris Cooley is just that.
Seen here famously wearing short shorts (or hot pants) at practice, Cooley, or "Captain Chaos" is always quick to make light of any situation. Cooley has quite a collection of YouTube videos, doing everything from a Redskins fantasy football draft to fighting with his OnStar.
Cooley's blog gives you insight into his day-to-day life (and one time, an accidental sight of a certain part of his anatomy). Finally, take a look at his pre-game countdown, which sometimes includes yelling some rather inappropriate words as loud as possible during the team meeting.
