I think the world would be way cooler if we would have domesticated the bear instead the horse. Oh you pranced around, jumped a stick and ate some hay? Big deal, my bear just ate a hobo, paw'd a bee hive then roared so hard deaf people heard it.
I sure am glad they give me a lead vest when they're giving me x-rays at the dentist. It gives the impression those rays must be dangerous. I'd hate to have something bad happen to my chest while I'm having dangerous x-rays shot into my head.
