Real citation: “Even if you love All Things Potter, it's hard not to be tired of Harry Hype. Obviously, it's not Harry Potter's fault that his bespectacled face is everywhere you turn, on every tv screen, book- and toy-store window. He's only 11. And fictional.

Made-up citation: "Ignore my black clothing and new, gone-to-the-darksidey, British accent. That's not blood on my hands; it's boogers on your brain!"
