Readers everywhere have fallen in love with the tale of a magical boy who escapes a decade of child abuse only to wind up in a facility with a worse child-safety record than the Industrial Revolution. Unfortunately, humanity's ability to simply enjoy the Harry Potter books and get on with their lives ended the very second two computers were connected together.
These days, the rule of fandom is anything worth doing, is worth overdoing, often to a terrifying degree. Just take a look at...
The Wizard Rock Festival
In what can only be an attempt by rogue mathematicians to create an actual physical empty set, someone organized the overlap of "Rock Festival Attendees" and "Hardcore Harry Potter Fans" in Brooklyn last September. If you've already guessed that the bands all had names like "The Cedric Diggorys" and "The Remus Lupins," well done on recovering from that attack on your faith in humanity faster than we did.
Tickets actually sold out, with 20 Muggle dollars earning you Wrock festival attendance (if you were wondering, yes, "Wrock" is "rock" about wizardly subjects). Though now that we look at it, it says about 300 fans and 17 bands turned up, a ratio that they could have managed if each band just got their friends and family to fork over the cash.
Behold the face of Wrocking Out:
Wait a second, that's... a lot of girls there. Maybe the young dudes in the audience know something the rest of us don't, like that guy we all laughed at when he made it onto the cheerleading squad.
