HBP: the Rude Bits

[mctabby]

I'm nowhere near finished HBP yet, but it's never too soon to start collecting for future reference! People might want to write fics about this book, after all.

So. Suggestive lines, double entendres, phrases that make you snigger immaturely and uncontrollably - please quote them in comments here.

P.S. Standard warning for spoilers. Dirty little spoiler-fragments, anyway.
