Q: In the Goblet of Fire Dumbledore said his brother was prosecuted for practicing inappropriate charms [JKR buries her head, to laughter] on a goat; what were the inappropriate charms he was practicing on that goat?

JKR: How old are you?

Eight.

JKR: I think that he was trying to make a goat that was easy to keep clean [laughter], curly horns. That's a joke that works on a couple of levels. I really like Aberforth and his goats. But you know Aberforth having this strange fondness for goats if you've read book seven, came in really useful to Harry, later on, because a goat, a stag, you know. If you're a stupid Death Eater, what's the difference. So, that is my answer to YOU.
