Now, I am 100% certain I watched that movie in High School at my friend Patrick's house. I distinctly remember doing it. Thing is, instead remembering the actual contents of the movie, my brain invented entirely new contents of the movie, including an ending where The Dude gets into a bowling match to clear himself of all the money people think he owes them. The whole "double or nothing" kind of deal. In the version of the movie I apparently completely made up, there were definitly no musical numbers, which were my favorite part of the real movie.
Am I just getting this movie confused with another slacker/bowling themed movie? Or am I completely fucking nuts?
