Winnie was really upset after being pranked by Randy. So she decided to get revenge on him. Mr. Baldwin blames Milo for Winnie's prank.
Nicole: When the car broke down.
Larry: Well, the damage in this school is only superficial. [Closes car hood] So it shouldn't cost more than a hundred dollars.
Winnie Grouper: A hundred dollars? EXCUSE ME!?
Randy: Better make that two-hundred.
Winnie Grouper: WHAT? [Breaks windows]
Randy: Uh five-hundred?
Mr. Baldwin: WHAT?!!
Larry: [Yelps] [Whispers] All the money in the world.
Winnie Grouper: Before I do what I'm about to do, I want you to know this is not your fault. You're just doing your job, but someone has to suffer for what happened and unfortunately you're the only one around. [Inhales deeply]
[Her head grows big, and she becomes very, very furious, she also screams in a very extremely demonic voice.]
Winnie Grouper: YOUR PRANKS!!!! IF ANYTHING BAD HAPPENS TO MY DAD, I'M GONNA RIP YOU APART AND TURN YOU INTO A POPCORN POPPER!!!! [Returns to normal] [Sighs in relief] I think that's all there was.
Randy: Uh. Would you like to ?
Winnie Grouper: Sure, a little extra twelve percent? [Inhales deeply] [Her head grows big, and she becomes furious again. She swims to cooking class.] [Flashback ends]
Winnie Grouper: Anyway, I feel much better now. (Penelope was shocked) That teaches him a very good lesson.
Penelope: You know what I think? [Inhales deeply]
[Penelope's head grows big, and she becomes very, very furious, she also screams in a very extremely demonic voice.]
Penelope: ARE YOU CRAZY!!!!! WHAT'S WRONG WITH YOU!!! RANDY MAY BR A PRANKSTER BUT YOU CAN'T PRANK HIM!
Winnie Grouper: I can't?
Penelope: No. But you can stop him.
Mr. Baldwin: Milo, get in here!
Milo: What's up.
Mr. Baldwin: I was bamboozled by ----- and it's all your fault!
Milo: What! (angry) What are you talking about, I wasn't even there!
Mr. Baldwin: Enough! I'm the boss and I can make my own rules if I want to!
