Malcolm in the Middle, Season 1

Malcolm:
They have a fake letter. I knew Francis wouldn't leave us alone without getting something, and I knew you'd give it away. I knew exactly what everyone would do.

Reese:
So where's the real letter?

Malcolm:
I had to think of the one place they'd never think of looking. I had to give it to the one person they'd never think I'd give it to. I did the most brilliant thing of all: I gave it to Dewey.

Dewey:
And I hid it under Mom's pillow.

Malcolm:
You WHAT?!
