The whole of withnail and I needs a quote ... This bit in particular
Withnail: I've some extremely distressing news.
Marwood: I don't want to hear it. I don't want to hear anything! Oh God, it's a nightmare, I tell you, it's a nightmare.
Withnail: We just ran out of wine. What are we gonna do about it?
Marwood: I don't know, I don't know. Oh God, I don't feel good. Look, my thumbs have gone weird! I'm in the middle of a bloody overdose. Oh God. My heart's beating like a ****ed clock! I feel dreadful, I feel really dreadful!
Withnail: So do I, so does everybody. Look at my tongue; it's wearing a yellow sock. Sit down for Christ's sake, what's the matter with you? Eat some sugar.
