'Weasels — and stoats — and foxes — and so on. They're all right in a way — I'm very good friends with them — pass the time of day when we meet, and all that — but they break out sometimes, there's no denying it, and then — well, you can't really trust them, and that's the fact.'
Rat, Ch. 1 - The Wind in the Willows (1908)
