- Cheatsy Koopa: Did you see the look on that brat's face when we heaved him into the Pipe Maze?
- Luigi: Oh, no! Junior could be lost there forever!
- Mario: I'd hate to have to tell that to his mom!
- Kooky von Koopa: Okay, guys! I think it's time we heated things up in the Pipe Maze!
- Bully Koopa: Yeah, this oughta parboil those pain-in-the-tail plumbers, and their little Brooklyn brat!
- Junior's Mom: Now where is that babysitter?
- Junior's Dad: Well, y-y-you don't think Junior's bad reputation could've scared him away?
- Junior's Mom: Now don't be silly! Junior's a wonderful child.
- Junior's Mom: So there you are! You must be the babysitters. I guess Junior let you in the side door, and I am so glad there are two of you, because Junior is quite a handful.
- [gives Luigi a book]
- Junior's Mom: Here's the phone number of our doctor, this one's for the theatre.
- Mario: But, uh, we're not...
- Junior's Mom: Snacks are in the fridge. Help yourself to lasagna.
- Mario: Lasagna?
- Luigi: But we're not...
- Mario: Shh! That lasagna looks good!
- Junior's Mom: [to the Mario Bros] We'll be back by 10:30, and could you please give Junior a bath? Have a nice evening. I know we will!
- [gets in the car]
- Junior's Mom: [to her husband] Quick, let's get out of here fast, before they change their minds!
- Junior: Say, just in case those dopey brothers follow me here, could you guys help me have some fun with them?
- Cheatsy Koopa: Kid, this could be the start of a beautiful friendship!
- [after trapping the Mario Bros. inside a volcano]
- Junior: That was so cool!
- Kooky von Koopa: Yeah, but the best is yet to come!
- [Kooky starts turning the valve to some pipes]
- Junior: Hey, guys, this is just for fun, isn't it?
- Kooky von Koopa: Of course it is, and I'm having a great time!
- Junior: Kooky, what are you doing anyway?
- Kooky von Koopa: Filling the cave up with lava, silly. What does it look like?
- Cheatsy Koopa: Look, kid. You've been real helpful, but the truth is, Junior, we really don't like you very much.
- Bully Koopa: Which is why we're getting rid of you.
- Kooky von Koopa: Right now!
- [the Koopalings toss Junior into a pipe]
- Junior's Mom: Junior! We're home!
- Junior: Uh-oh. If I don't get my bath, Mom will never let you babysit for me again.
- [Mario and Luigi rush upstairs with Junior]
- Junior: That is, if you ever wanted to.
- [Mario brings in Junior as Luigi fills up the bathtub]
- Mario: Now hold your breath, Junior, 'cause we're taking a dive!
- [Mario tosses Junior into the tub and the bubbles get on the Mario Bros., covering their raccoon ears and tails]
- Junior's Mom: [enters the bathroom] Junior, where are you?
- [notices Junior in the bathtub]
- Junior's Mom: [gasp] Why, Junior, I don't believe it! You got Junior to take a bath! Do you think Friday you two would babysit again?
- Junior: Oh, boy, that would be super!
- [Mario and Luigi are less than pleased to hear this]
