Dewey: [to the dog] And then Dewey and Marshmallow killed the evil dragon, rescued the poor little princess and flew all the way back home. And they got medals and big red capes and everybody loved them.
[Reese opens the bedroom door and tries to waft the smell of roast beef into the room]
Dewey: [Marshmallow groans] Are you OK? [Marshmallow runs out of the room] Marshmallow!
[When the boys catch up with Marshmallow, he's already up on the kitchen table eating the roast beef.]
Dewey: Marshmallow, stop!
Lois: [o.s.] Boys, I told you to stay in your room!
Dewey: [whispers] Marshmallow, hide!
[After the dog runs away, Dewey climbs up on the table and sticks his face in the roast beef]
