I just pulled up the list, Kevin; it's been quite a while since I saw it, and it seems a lot of movies have been counted since I last perused it - BL (with 260 Fs) is now #14. Pulp Fiction (265) & Reservoir Dogs 269) are 13 & 12. The current leader is an eponymous documentary on the word, whose 824 uses & 8.86 uses per minute both pretty much quadruple Lebowski's not-inconsiderable totals. It was a tough challenge - but by God, they went out and achieved anyway- without the use of their limbs, which some Chinaman took from them in Korea!
Peter (And before someone is offended by that paraphrase, allow Walter Sobjak to correct me - ..oh, and Dude - Chinaman is not the preferred nomenclature; Asian-American, please.)
