I just saw one of my little cousins. I commented on his cap, which said "Grave Digger". I noted out, that's a pretty great German power metal band, made a quote from this particular song (link below) and he was amazed, that I recognized them. I just told him "I do know my metal, dude", before walking off. He is in his early twenties. I must seem like a dinosaur to the youngsters.
