THANK YOU, A THOUSAND TIMES, J.K. ROWLING. From waiting for acceptance letters from Harry's wizarding school, sweating it out in queues outside bookstores all night to lay hands on fresh copies, to having Harry Potter theme-based weddings, Potterheads (official name for Potter fans) are one crazy bunch! One can't blame them, though. The Harry Potter series, is in one word, life-changing. (Photo | AP)
