He thinks he's so clever, just because he has the Answers to Everything. Well clever you might be, but I stole those Answers right and proper... possession is nine-tenths of the law, and more to the point I ruined a thoroughly good shirt in the getting of them. So he can't just stroll out of here with what's rightfully mine! Now who's doing the stealing? Isn't there any honour amongst thieves? And he used magic, which isn't fair either.
I am the Concuspidor! I insist I am still splendid! Fisticuffs will settle this! Fisticuffs plain and simple, with no magic, which is cheating, since it's something Wizards always have the advantage in. Fisticuffs, man-to-man, the noble art of pugilism, an honourable settlement. And if I put a sprint on I can catch him at the doors and thump him from behind before he knows what's hit him.
