In reply to Blue Straggler:
> The Big Lebowski....I mainly associate it with David Thewlis' weird and deliberately annoying laugh, in the scene where The Dude properly meets Maude Lebowski for the first time. Not the bowling, not the Nihilists, not the toe, not the big fantasy dream sequences. Thewlis' laugh.
Absolutely! My very favourite scenes in the movie. "Look I'm sorry if your stepmother is a nympho, but... have you got any Khalua?".
There aren't any "classic" scenes in Living in Oblivion, but the line I remembered from the first time I saw it was, "I freak out in my dream, I freak out in your dream...no wonder I'm f*cking exhausted!". A year cannot go by without a viewing of that film.
Not to answer your question in a different way, this isn't possible with Withnail, because every single scene is classic. But "leg bound in polythene" has become an everyday part of my vocabulary (since I moved to Cumbria).
