This is how Stu Pickles makes the Reptar Wagon in Weekenders Adventures of The Rugrats Movie.

(Cut to basement, where Stu and Drew are arguing.)

Stu: Pushy!

Drew: Lazy!

Stu: Bossy!

Drew: Inconsiderate!

Stu: Nosy!

Drew: Good for nothing!

Stu: Busy-body!

Both: Why can't you listen to me?!

Drew: We're talking about a real job, Stu, with benefits.

Stu: I'm not going to waste my life as a clock-punching, paper-pushing, bean-counting... Oh, no, offense.

(Stu proceeds to weld.)

Drew: You barely make ends meet now. You've got no insurance, no savings, and another kid on the way!

Stu: For your information, bro, I am working on something right now that is going to put this branch of the Pickles family on Easy Street.

Drew: What is it this time, huh, an electric sponge?

Stu: Of course not! That was last year. (reveals a skeleton of the Reptar Wagon) This, this is the Reptar Wagon! The ultimate in toddler transportation. The perfect children's toy!

(Grandpa fixes an old radio as he talks.)

Grandpa: In my day, we had plenty of fun just throwin' rocks at each other. Big bag of dirt clods, that's what the kids want.

Stu: The Reptar Corporation is holding a toy design contestM and the winner gets $500!

Drew: (sarcastically) Ooh!

Stu: And there'll be plenty more if this toy's a hit, and I'll be famous!

Drew: Oh, yeah, yeah, yeah. That's what you said when you built that stupid thing.

(Drew points to a Dactar glider, which is suspended from the ceiling.)

Stu: Maybe Dactar was a little...complex, but... this...! (speaking into microphone, in normal voice) I am Reptar! Hear me roar!

Reptar Wagon: (Stu's voice, distorted) I am Reptar! Here me roar!

(The Reptar Wagon spits fire.)

Grandpa: Dang-flabbit! Can't a man work in his own basement without gettin' barbecued?

Stu: Okay, so maybe real fire isn't the best idea for a children's toy.

(Drew's shirt is smoldering; Stu sprays Drew with the fire extinguisher.)
