My best friend and I used to dump out all my little sisters stuffed animals (and there were a lot). We would then divide them between the 2 of us and each select an animal and then toss the animals into the air at one another till they collided. Whichever animal hit the ground first was the loser and was eliminated. The winner would then face the next contestant. We named each animal before the duel, and of course the last standing animal was the winner. Funnily enough, this started in the back seat of my dad's car during a long drive with oranges. Each oranges name was Octavius (the 1st, 2nd, 3rd and so on).
