Fry, Leela and others in “The Mutants Are Revolting”

Fry

I'm so sorry I ratted you out, but, you know, after two weeks down here, I'll truly understand the plight of the mutant people.

Leela

How dare you? You wanna understand something? Look at that lake. One dip in that toxic muck and your DNA will be permanently mutated. You'll grow a camel hump, or a Zoidberg face!

Zoidberg

[freaked-out] Urgh!

Leela

You want to know what it's like to be a mutant? Jump in and go for a swim.

Fry

I would, but I just ate a bunch of potato salad, so...

Leela

Yeah. That's what I thought. You are all surface.
