With almost any other screenwriter or screenwriters, this scene — this line, I mean — would just a good, vulgar, funny throwaway. But with the Coen brothers, it’s an integrated plot thread. Because Tara Reid‘s Bunny Lebowski really does need money, and to such a degree (we’ll eventually learn) that she’ll soon be a willing pawn in a fake kidnapping plot. This is what good screenwriting does. It decides that even a seemingly innocuous sex gag will feed into the whole.
