I thought I'd seen it all until I stumbled upon this video of a cat performing a stand-up comedy routine for a crowd of chickens. This feline has some serious talent! By the way, did you know that there's a species of jellyfish that is almost immortal? Turritopsis dohrnii can revert back to its juvenile form after reaching maturity, effectively resetting its age. Who needs anti-aging creams when you're a jellyfish?
