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.
