Hal: Er, honey? We're back.
Lois: Hey, guys. Why don't you wash up, dinner's ready. I made your favorite - meat loaf and mashed potatoes.
Dewey: OK.
Reese: Great.
Malcolm: Why isn't she mad?
[When the boys go into their room, it's been stripped of everything but the empty, basic furniture]
Dewey: What happened?
Reese: All our stuff is gone!
Lois: That's right. I gave it all to charity. You now have two changes of clothes - one for school, one for home. Something wrong?
