Avon's vicious snark is always funny.
Vila: When you get Zen [the computer] working, ask him to prescribe something for a headache, will you? I've got this shocking pain right behind the eyes.
Avon: Have you considered amputation?
Blake: Does it support any intelligent life?
Avon: Does the Liberator?
Jenna: I thought they [alien plants] died if they left the planet?
Cally: No. You have to talk to them.
Avon: That's like talking to Vila. A complete waste of time.
Avon: How long a list would you like?
Gan: Can't find Orac [a computer]. Even tried calling his name.
Avon: Oh, I'm sorry I missed that. That's the kind of natural stupidity no amount of training could ever hope to match.
