There's a guy who lives in my city with Dragon Ball Z and GT characters tattooed all up and down both his arms, and it looks really awesome. I don't personally like DBZ that much, but if you're a fan of something and you're okay with having that character or object on you for the rest of your life, then why not? Shit, I've been contemplating getting tattoos of some of my favorite characters, including Shadow, Mewtwo, Vegeta, Lucario, Donatello and Bumblebee. I don't have a tattoo yet, but I think I might like one of them to be one of my favorite characters.
When the first Pokegames came out, I tried playing one at a Game Boy display in Wal-Mart. I hated it, and never touched the franchise again, except for a brief attempt at extorting money from six year olds at Pokemon card game tournaments.
