The forms of revenge that Lois uses are:
1) Bubblegum in the hair, ensuring that the first girl would have her hair cut off.
2) The decapitated and mutilated heads of the second girl's dolls and stuffed animals stuffed in her locker.
3) At the third girl's house, Lois placed a pink duffel bag with condoms and hotel brochures inside her living room, then made a call to her parents, pretending to be calling about a hotel reservations for the romantic suite. And she accidentally framed the next door neighbor's son being a pervert while making her getaway.
4) After talking to Reese about what she had done, Reese wanted to continue the revenge, so they borrowed Hal's pitching machine and made a catapult with paint balloons.
Lois mentions at the end of the episode that she and Reese should go bowling sometime, which relates to the season 2 episode, "Bowling."
This is the episode where we find out that Lois has a "bully side" like Reese.
Why would two people being pelted with paint-filled balloons not take cover?
Malcolm: Tell me, did it feel good to cut through Elmo's neck?
Lois: I've been a terrible mother.
Reese: It's okay, Mom. I've known that for a long time.
Lois: Are you trying to calm me down?
Hal: No. I just don't think it leads anywhere good when you get like this.
Lois (quietly): Get like what?
Hal: Well... you know.
Lois: No, I don't know. How is it I get?
Lois: If I have a problem, I would love for you to explain it to me.
(pause; Lois continues glaring at Hal)
Hal: You know what, honey? This seems like a-a much longer conversation, and it just so happens that I am right in the middle of a project in the garage.
Hal: And I actually think that Reese is coming around a little bit.
(Reese is heard crying in the distance)
Hal: Well, I brought him soup yesterday, and he couldn't even make a sound.
There is no "Camera Commentary" in this episode.
Cold Open: Reese ruins the denim shirt Lois gives him so she fixes it for Malcolm. He ruins it too so she makes shorts for Dewey. Dewey says he won't wear them anymore because they are too short so she makes Hal a denim tie.
Christopher Masterson (Francis) does not appear in this episode.
