Beekay! Bad dog! No eating alien spaceship captains in the house.

I suppose you find me delicious as well.

Ugh. No. The mere thought of hurting an intelligent being, much less eating one… ugh!

I don't know if it's a programmed safeguard or your upbringing, but either way it makes me feel a lot easier about having a deathworld carnivore as my engineer.

A reference to Harry Harrison's Deathworld? ([user>KALDYH]]).
It's just another widespread concept in English-language fiction. If it's going to be considered a reference, it's got to be HFY (and even that's questionable), where the Earthworlds were “DeathWorld” for all the other races. (anon)
