"I'm not George, I'm Fred," said the twin he had just addressed, rather indignantly. As it was in fact the one Angelina had called Fred less than thirty seconds ago, this was a plausible objection, but Percy was entirely unapologetic. He just rolled his eyes, and gave George a deeply skeptical look. There was a distinct silence; and then after it had stretched on uncomfortably for awhile, George gave up. "Fine, I am George," he admitted mulishly. The only thing the twins had never been able to pull on Percy since they began Hogwarts was the twin switch, though they had never stopped trying. It frustrated them to no end that he could invariably tell them apart, and refused to explain how.
