Francis: Boys, the time has come. You're about to see the device that will change the face of Halloween forever. Behold.
Dewey: That's not a flying chocolate maker.
Reese: This is just a bunch of tubes.
Francis: Trust me.
Reese: I do trust you, but... I expected something a little more...
Malcolm: [looking at blueprint] Oh, my God. Will this work?
Francis: Absolutely.
Reese: What? What is it?
Malcolm: It looks like an incredibly powerful slingshot.
Francis: A slingshot capable of hurling objects over a distance of two city blocks. Picture yourself you're walking down the street, you're minding your own business when all of a sudden... bam! You're hit by a ten-pound balloon filled with shaving cream, paint or any number of foul-smelling liquids. And you never, ever know who did it.
Reese: It's the perfect weapon.
Malcolm: Reese, are you crying?
Reese: [emotional] No.
