Malcolm in the Middle, Season 4

[Reese comes in as Billy is doing Dewey's homework and doesn't think anything awry.]

Reese:
With Billy Prescott as our fall guy, we can do anything. Now, I've updated my enemy list.

[Reese is in the shock of his life when he sees Dewey dressed up like Billy and Ira waiting for him.]

Dewey:
Are we even?

[Ira gleefully agrees as Reese tries to pin the blame on his own non-existent look alike. He soon realizes the game is up and gets beaten up by Ira.]
