Season 5, Episode 7: "The Nonfat Yogurt"

There's nothing more fun than cursing when you're a kid.

I mean, it's like gettin' the keys to the car, isn't it?

You're doin' something you're not supposed to do,

and that's all you want.

And there's nothing less fun

than when you're an adult,

and having to use those wholesome curses.
