I haven't been into wrestling in decades, but Mick Foley is definitely one of the greatest. He wore a lot of hats well, and he put his body through so much fucking punishment for our entertainment (hell, a lot of wrestlers do, actually).
It also doesn't hurt that he's a genuinely good guy outside of the ring, which, often, seems like a rarity in the industry. At least back in the day when I was big into it.
