Pit bulls, pirahnas and Venus fly traps

Ray, picnicking with his friend Lena in the park, chats about keeping a pet.
...

Ray: I'd like something with a bit of character.

Lena: A pit bull.

Ray: No way. Genetic manipulations. Not a dog. I was thinking a fish.

Lena: Piranha?

Ray: You sink a couple of glasses of chardonnay and you go more aggressive than me. Anyway, they get too ferocious and you can't put anything else in the tank with them. I couldn't toss them in the river like some punch-permed yakuza would.

Lena: Venus fly trap?

Ray: I could live with one of those. A plant housekeeper.

Lena: Hypocrite! They're all carnivores, just a question of scale.
