Wanna get acquainted with blue tits, weasels and yaks?  Check out this link to BBC's Animal Facts Page.  The information here may help you create a new Inter-Species survivor debate for you and your stoner friends to talk about over cold pops and cheesies - you can't talk about sex forever, you know.
You decide....
Who would win - in a fair fight?  Neutral terrain.  Both fully grown. Both pissed at each other.  Check out the facts.  Add your own spices to the argument, and then think of a new challenge.
I'm telling you, folks, this is hours of fun. All you need is a few drinks and a lull in the conversation, at which point three words will do the trick,  "Who would win?"
A Hippo or a Polar Bear - IN THE WATER?  In Africa, more people are killed by hippos than any other animal, but the Polar Bear is the largest land mammal in the world, and is a great swimmer - WITH HUGE CLAWS.  That's good stuff.
A Camel or a Kangaroo?  The kangaroo is a lot smaller, but can kick the grease out of a burrito (?). The camel spits, too, which has to be de-moralizing for any opponent - it also has an endless supply of water in their big 'ol humps.  Woo hoo, what a doozy.
Let's not forget the little guys. Snapping Turtle, and a Rabid Aarvark.  The Aardvark may be the first animal in the dictionary, but he's the last critter I'd want to mess with - especially if he's foaming.  And snapping turtles are known to, well, snap.  I got nothin'.
A Giant Panda or a Cougar?  A Grizzly Bear could probably take a cougar under normal circumstances, but what about it's distant, and slightly less formidable cousin, the Panda?  They're known to be grumpy and fierce when cornered.  Grrrrrrrrrrrrrrrrrrrrr.
Or how about checking out the craziest bastard you'll ever meet.  Steve, the "Crocodile Hunter" would surely enter a few good arguments into our little game here.  A Croc or a hippo, Steve?  "By crikey, I reckon the hippo would make a fair tucker out of any crock inside 12 feet!  That's a good boy."
