Hanging my head in shame -- not really

So we used our lottery winnings to buy a new stove and over-the-range microwave/convection oven combo. Yes, we are total geeks. I supervised the delivery this morning and called M to tell him all was well.

M: Have you cleaned it all yet?

C (pauses): How did you know?

M (laughs): I know you too well.

Indeed he does.
