Meet Marvin. He's a big, bald, uber-hard, prison block type of guy with neck/face/sleeve tats and lots of flashy gold chains. In otherwords, Marvin looks like the type of dude who would take a lot of pleasure in beating your ass into hamburger with metal chains if you f-cked with him. But even Marvin has his own kryptonite: cute innocent puppies. He's the subject of a new episode of Animal Planet's "My Extreme Animal Phobia," which shows him breaking down into tears at the site of an adorable pitbull puppy. Oh, the horror! Let's watch the promo, which showcases his puppy-induced emotional meltdown.
