The way they talk in the movie
This really is one of my favorite films but I don't get why they all refer to each other as "Lady". Like Dexter Gordon will walk into the apartment building and Ace is standing there in his robe and slippers with a bowl of something he just cooked up and Dex will go "Hey, Lady Ace! Whats happenin'?"
Another thing too... Whats up with that part of the film where they ask "Do you like basketball?" What does that have to do with anything? It just seems really random and they don't explain it.
