SpongeBob SquarePants, Season 8

Sheldon J. Plankton:
♪Oh, Santa, Santa, Santa has his eye on me. He's seen everything I've done. Every plot, plan, and scheme. It's just a bit of fun. Santa has his eye on me. Every naughty deed is written in his scroll. So every Christmas morning, I get a stocking full of coal!♪ [Dumps out coal from his stocking]

Karen Plankton:
Maybe you'd get a real present from Santa if you weren't the biggest jerk in Bikini Bottom.

Plankton:
I'm way ahead of you, Karen! [Periodic Table lowers from ceiling. Plankton walks over to it and sticks a piece of notepad paper on it. The paper says Jt for Jerktonium] There is one element in the known universe that can turn even the nicest sap into the biggest jerk they can be! And I, Plankton have discovered it. Behold! [Plankton pulls a lever] Jerktonium! [A piece of Jerktonium contained in a glass capsule lowers from the ceiling] I'll give everyone in Bikini Bottom a present of the most innocent of all holiday goodies. The fruitcake! [picture of a fruitcake appears on screen while he says the fruitcake] And each and every slice will be laced with Jerktonium! Once ingested, no one can help becoming the biggest, creepiest, meanest jerk ever! Then Santa will realize that Sheldon J. Plankton isn't so bad after all! And then I'll finally get what I really want for Christmas, the Krabby Patty secret formula! [Plankton jumps on an oven and holds the fruitcake] And now for the main ingredient, Jerktonium! Okay, Jerktonium, do your stuff! It's complete! [Laughs] Ha ha! The Jerkmaker 9000 will make doling out tainted fruitcake a breeze! Now, who's gonna be my first victim?

SpongeBob:
Hey, Plankton! What've you got there? [Gasps] Hey! Is that a fruitcake dispenser? You don't suppose I could have a piece, do ya?
