One of my all-time favorite films, Witnail & I:
Marwood: I wouldn’t drink that if I was you.
Withnail: Why not?
Marwood: Because I don’t advise it. Even the wankers on the site wouldn’t drink that, that’s worse than meths.
Withnail: Nonsense. This is a far superior drink to meths. The wankers don’t drink it because they can’t afford it.
[He pours the lighter fluid down his throat. He gags and gasps]
Withnail: Have we got any more?
[Marwood shakes his head]
Withnail: Liar. What’s in your toolbox?
Marwood: No, we have nothing. Sit down.
Withnail: Liar. You’ve got antifreeze.
Marwood: You bloody fool, you should never mix your drinks!
[Withnail laughs hysterically and falls to floor, and then vomits on Marwood’s feet]
