I honestly haven't rewatched Dances With Wolves in over 20 years, but I vividly remember that scene when the fat man approves Kevin Costner's transfer request near the beginning of the movie.
The strange dialogue: "I quickly deduced that you were an Indian lover. I did not get to this position by being stupid.", "You think I don't know?" "No sir, it's just that I don't know." "I've just pissed in my pants, and nobody can do anything about it!"
The fat man's mannerism are just strange: The way he takes a bite out of that biscuit (or whatever) and shakes his jowls. The way he hurriedly scribbles the approval letter. The way he mockingly returns Kevin Costner's salute in disdain.
That whole scene is etched into my memory for some odd reason. The funny thing is that it could be removed from the movie entirely and it really wouldn't affect the story at all.
- Edit: The actor's name is the late Maury Chaykin. He's been living rent-free in my head for so long. I should at least show him some respect.
