Quote from Lois in Hal's Birthday
Dewey: [screams] Reese: Get back, you little weasel! Lois: Reese! [As Lois stops herself from screaming, she calmly pulls out a notepad and pen and writes a note that she then hands to Reese] Reese: I'm sorry, I'm sorry, it's all my fault! I'll clean my room and do all my homework! Malcolm: [to camera] We may wanna go back to the old system.
