I think the actual count in the motion picture is 281 F-bombs, and that was most of them. The crazy thing about it is that is you have seen the movie as many times as I have, it kind of tells the story.
As an added bonus, here is the second greatest f*cking movie ever. (also NSFW)
Casino has 398 F-Bombs, the third highest in motion picture history, but if you add in all the swears in the movie you get 534 swear words, which the the highest-ever in a motion picture. The more you know, huh?
Wow, I had no idea they cussed that much in The Big Lebowski (Larry Brown Sports)
