Then of course there's the live organ transplants scene from "The Meaning of Life":


MR. BROWN:
Yes?
MAN:
Hello. Uhh, can we have your liver?

MR. BROWN:
My what?
MAN:
Your liver. It's a large, ehh, glandular organ in your abdomen.
ERIC:
[sniff]
MAN:
You know, it's, uh,-- it's reddish-brown. It's sort of, uhh,--
MR. BROWN:
Yeah,-- y-- y-- yeah, I know what it is, but... I'm using it, eh.

ERIC:
Come on, sir.
MR. BROWN:
Hey! Hey! Stop!
ERIC:
Don't muck us about.
MR. BROWN:
Stop! Hey! Hey! Stop it. Hey!
MAN:
Hallo.
MR. BROWN:
Ge-- get off.
MAN:
What's this, then? Mmh.
MR. BROWN:
A liver donor's card.
MAN:
Need we say more?
ERIC:
No!
MR. BROWN:
Listen! I can't give it to you now. It says, 'in the event of death'. Uh. Oh! Ah. Ah. Eh.
MAN:
No one who has ever had their liver taken out by us has survived.
MR. BROWN:
Agh.
ERIC:
Just lie there, sir. It won't take a minute.
