I'm not sure if this counts, but I met this guy at amoeba in hollywood back when i was in middle school. I was there to buy Green Day's American Idiot, and i ran into him, and he was like we talked a bit, and he told me he was a bassist, so we talked about basses for a but(i played bass back then). Then he handed me the Blink-182 album and told me i should check them out, they're pretty cool. Later on I found out he was the bassist for Blink 182, and I was like holy shit.
