There will be people there for humor value, there will be people there with fond memories of Hotwheels. Somewhere there will even be people who still regularly listen to Uncle Luke non-ironiclly, who don't immediately say "man, that's so Miami" between songs or while the cassette in their Tercel's stock audio system changes sides.
There will be people there because it's funny, because it's a spectacle, because it's nostalgic, and just because it's awesome. But you know who won't be there? Me. Why? Because I too vividly remember getting my ass kicked in 6th grade for listening to Pearl Jam. Also, I'm completely exhausted.
