Meet Emperor Tamarin. Not sure what he's the emperor OF, but I'm sure it's some balla-ass part of the jungle where we all wish we could be.
Now, if you didn't notice, this thing has an epic 'stache. I mean, seriously, I could try for years to pull something like that off and would only come in about half as badass. Just because I think you need to see more, I'm putting a handful of pics after the jump of what I consider to be the best of the best when it comes to these guys.
If you actually want to learn something about them, go to the wiki. But, to be honest, there's not much else interesting about them.
