[What's a wizard to do when his garden is infested by gnomes? Well, if you're Mrs Weasley, you get your children to get rid of them. If you're Sirius Black, you turn into Padfoot and chase them off. So if you should happen to see a large, vaguely-ominous black dog running through a garden, he won't bite. Unless you're a gnome. Or you ask really nicely. To some, he might even look familiar.]
