A Simpson's THOH Transformation Story.

Bart comes into Lisa's room and does something that even he knows is very tactless. He walks up to her at her desk and pokes her in her butt saying. "Heh Lisa. You might wanna cut down your food intake your butts getting kind of big." At first Lisa is to stunned to say anything but then she just calmly gets off her chair faces Bart and yells at him. "BART! HOW DARE YOU? GET OUT! GET OUT! GET OUT!" Bart just smiles knowing he's getting a rise out of Lisa and on the way out before he shuts the door he says. "Seriously Lisa. Co's you know if you carry on like this your gonna end up as the school fatty!" He then shuts the door and Lisa makes a "mmmmrrrrrr" noise and goes to pick up her stress ball which she squeezes while saying. "Only ten more years, only ten more years..."

Lisa calms down a bit but is still angry and she grabs a pencil and begins to write about Bart and what he said to her. How can he be so insensitive? Why does he have to be such a jerk? Etc. Eventually she gets to writing about the fact that Bart is more than a little chubby himself and starts calling him "tubby" or "fatty". This is just Lisa exaggerating a little because she is angry and because Bart was being a hypocrite but the book takes it as instructions to make Bart fatter. Soon it works it's magic and Bart is going to be the fattest Simpson kid by a mile but will he get fat all at once or will it happen over several days?
