“Ah,” said Dumbledore gently, “yes.  Yes, I thought we might hit that little snag.”
“Snag?” said Fudge, his voice still vibrating with joy.  “I see no snag, Dumbledore!”

“Well,” said Dumbledore apologetically, “I’m afraid I do.”

“Oh really?”

“Well — it’s just that you seem to be laboring under the delusion that I am going to — what is the phrase?  ‘Come quietly.’  I am afraid that I am not going to come quietly at all, Cornelius.  I have absolutely no intention of being sent to Azkaban.  I could break out, of course — but what a waste of time, and frankly, I can think of a whole host of things I would rather be doing.”
