A/N: I DISCLAIM!!!
Ok, picture this scene as a nice, small Weasley gathering. Harry and Ginny start out talking
"Should I tell them, or you?"
"I think you should."
"But why, Gin? It's your news."
"But Harry, knowing you, you would shock them into next week."
"Erm, you do know we're right here?' Ron interjected.
Ginny and Harry looked at each other. A silent agreement passed between them, and Harry turned to the rest of the family.
"Ginny's a Harpy."
Ginny's elbow connected sharply to his stomach and Hermione's hand smacked him upside the head as the entire Weasley family choked and stuttered on their food.
Mrs. Weasley gasped, "Harry James Potter! Why I never! How could you say such a thing?"
"Yes," Harry continued as if he had not been interrupted, "A Holyhead Harpy. She tried out and made the Chaser position."
Bang
Four Weasley brothers simultaneously hexed Harry. When they were through, the end product was a black-eyed, bright green ferret with purple polka dots.
"What was that for?" yelled Ginny, rounding on her brothers.
"That was for calling our younger sister a harpy!" said Bill, seething.
"I wonder why he did it, though," said Percy thoughtfully, "I mean, in front of everyone like that."
"That's because I AM a Harpy," Ginny shrieked, "A Holyhead Harpy. If you had just bloody listened to him before hexing him, you would have known that!"
Mr. Weasley, who had just sat there in mild amusement, put Harry back to normal, discreetly leaving the purple polka dots in his hair.
"Well, that's the last time I go along with one of your plans, Ginny." said Harry, dusting himself off.
He found himself subjected to a particularly powerful Bat-Bogey Hex.
