"I'm so scared of you my spine has turned to jelly, it's just that I'm suffering from an overdose of terror right now. I mean, when I've got over that then I'll have time to be decently frightened of you."
"He'sh mad?" "Sort of mad. But mad with lots of money." "Ah, then he can't be mad. I've been around; if a man hash lotsh of money he'sh just ecshentric."
He'd always felt he had a right to exist as a wizard in the same way that you couldn't do proper maths without the number 0, which wasn't a number at all but, if it went away, would leave a lot of larger numbers looking bloody stupid.
