Season 3, Episode 10: "The Stranded"

-Are you a vegetarian? -Here we go.

Yeah. I eat fish occasionally.

-So you're a hypocrite. -Hey!

I've eaten frogs, so nobody's perfect.

-Talk to me when you stop eating fish. -Fish don't feel any pain.

How do you know? Do you communicate with fish?

Well, they're not kept in little cages.

-Ever seen a goldfish? -Goldfish!
