Talk about some bad decisions...
That one with the eyeball on his head is airbrushed. Some of these tattoos show some real inspiration and innovation. Others show what a complete fucking lack of understanding some people have as to how drastically their lifestyles and tastes can change between their twenties and thirties. Just imagine those guys with the homosexually oriented tattoos going straight later on. Friends don't let friends get sucky tattoos.
Oh, here's one other bit of sage advice: What makes you cool before age 25 suddenly makes you a colossal fucking loser afterwards. Drugs use, being a fashion victim, thinking you can dance, having a Firebird, being good at video games, heavy drinking, weird, gory and/or copious tattoos, etc. You get the idea.
