Another missed joke

It's another of those HP jokes I hadn't quite grasped
until now. When Dumbledore tells Karkaroff about the
chamber pot room, Harry thinks he is joking, to Percy's
disapproval. What I only just noticed for the first time
is that Dumbledore's comment about a full bladder is a
signal that it *is* a joke. He is saying, for those with
ears to hear, that he is taking the piss.

Mmmm...never heard that one. I don't think it matters,
actually. Dumbledore's comment about having a full
bladder is suitably snarky without having a double
meaning. You might be right, of course, but I don't
think it was intentionally written that way - it's a
long way to stretch for a pun.
