The scene begins, a dark room becomes slightly lit as an arm chair turns around, revealing Bart Simpson sitting in it, holding a book. He does not open it. He speaks, "Do you have a dream that you want to come true? Perhaps you have actually been sleeping at night and had such a wonderful dream you wished it were real? What would it be like if your dreams actually came true? Or more so. . . Your worst nightmares? Here is a tale of a few people whose dreams came true, and it isn't very pleasant. . ." He started cackling a little, darkly, before opening the book, revealing the cover and title: "Treehouse of Horror XXIV and a Half"

Our tale starts with an eight year old girl. She is awaking from her slumber from the night before. "Thank goodness!" she says. "It was only a dream. It seemed so real; oh what could it mean? Don't be silly; dreams don't mean a thing. You'll always be at the top of the ranks! With your smart brains and your talent, too; you'll knock their socks off—they won't know what to do."

However after running down the stairs, little Lisa found her father already gone and her brother not there. "Lisa!" her mom said. "You have missed the bus. You better hurry; I don't have time to fuss!" So the girl hurried and scampered along, hoping that nothing else would go wrong. She ran into her classroom and was greeted with a frown as her teacher coldly told her to sit down. She said, "Lisa, you are very late; you are even later than the dumb child who eats paste!"

The class started to get underway, and Lisa figured things surely would be okay. Then, just as if things couldn't get any worse, she started spurting out all the wrong answers! Her teacher was shocked but did not hesitate to give the class genius her first failing grade. "Why you are acting this way is a mystery, but this day is certain to go down in history. Speaking of history, when did Columbus sail the ocean blue?" "Um," Lisa said. "1452?" After double checking her answer key, the teacher shook her head, disappointedly. "Another F! Accept your fate. I don't believe you'll make it to third grade."

The children all pointed and laughed at her some. Even little Ralph Wiggum said "Lisa, you're dumb!" She left the room crying; she ran down the halls, and unfortunately she had to trip and fall. She fell on her face and didn't want to look up, but as she did she saw the boy on whom she had a crush! How embarrassing! He'd seen! The nightmare continues. She thought to herself, "Lisa, you just can't win, can you?"

To make matters worse, right by the boy's side, was Jessica Lovejoy batting her eyes. Lisa started pulling at her hair, hoping to wake from this horrible nightmare. But alas, it was real, the boy only pointed and laughed. He said, "Ha ha! She's the weirdest girl in class. Come on Jessica, this girl's full of baloney. Would you like me to buy you a pony?"

The scene changes back to the dim lit room with Bart in his chair. "Well, that was it. The end of her nightmare. Or perhaps it was only the beginning? Everything she had dreamt the night before came true. Now this is a true story, I swear! It could happen to you so beware—your worst nightmares may come true just like little Lisa's did. . . Yes, I am aware I stopped rhyming. How can someone expect one to keep up with such phoney baloney!? . . Oh wait, that was a rhyme wasn't it? I think I'm cursed! Oh this couldn't be worse! Oh God, someone please take this book from me. Take it from me now!" He held the book away from him, covering his eyes with one hand.

His mother, Marge, enters the room and looks at him sympathetically, taking the book away from him. "Oh, was the book too scary for you, special little guy? I'll take over from here!" She pinched her son's cheek, tugging on it affectionately, causing the boy to grimace. He walked away rubbing his cheek with a scowl as his mother sat down and opened the book. "Oh! This one will be good. It's about Maude!" She started flipping through the pages, her eyes widening slightly. "Oh my! Are we allowed to show this?" Marge looked around. "I don't think this is appropriate. What about the children?"

"Oh, enough about the children!" A voice came from another room.

"Helen?!" Marge called back.

"For pete's sake, Marge, if you can't get the guts to read the book, I will!" Helen stormed over, grabbing the book from Marge's hands.

"No!" Marge pulled it back forcefully, causing the woman to fall over. She cleared her throat politely and opened the book back up to her place. She looked forward with a worried expression. "Now I'm not kidding; I hope you tucked your children in bed! This isn't going to be very appropriate. . .Okay, here I go." She began to read the next tale.
