That's right... it's Puppy War! It's a site that randomly pits two puppy pictures together, and asks you to vote for which one is the cutest. Spend five minutes there... I dare you. Soon you'll be like the Grinch at the end of the classic animated movie when his heart grows really big and breaks that measuring device. It's just that cute.
Oh yeah... and if puppies aren't your thing (but really... how can they not be?)... then there is also Kitten War.
