Another great metaphor.

I'm currently reading Terry Pratchett's Making Money because it's just out in paperback and I'm too cheap to buy hardbacks. Generally brilliant, of course — the man just keeps getting better. Well, apart from his health, of course, poor guy.

Anyway, specifically, further to his previous "gayer than a treeful of monkeys on nitrous oxide" and Achewood's superb "straighter than John Wayne voting for Reagan on a horse" (for which, incidentally, I am now the top Google result, which surely makes me A Man), Pratchett has now set the metaphor bar to a new high with

the girl could flounce better than a fat turkey on a trampoline.

Wow.
