SpongeBob SquarePants - Plankton and Karen in It's a SpongeBob Christmas

Towards the beginning of the series' stop-motion Christmas special, "It's a SpongeBob Christmas!", Karen suggests to Plankton that he might get a present from Santa if he were not such a jerk. Plankton proceeds to tell her about his wish to turn everyone else in Bikini Bottom into jerks using "Jerktonium"-laced fruitcake. This way, he will seem better in comparison. Later on, Karen reveals to Plankton that his scheme is flawed in that his fruitcake cannot affect SpongeBob. Karen's screen displays a diagram to explain that SpongeBob's innocence shields his heart from Jerktonium's effects. This inspires Plankton to sabotage SpongeBob's chances of getting a present with "Plan B," an evil SpongeBob wind-up toy.
