"I know it was you, [...]. You broke my heart." from The Godfather: Part II received just a single vote, finishing in fifth place.
"'Course I'm respectable. I'm old. Politicians, ugly buildings, and whores all get respectable if they last long enough." from Chinatown managed two votes, for a fourth place finish.
This category is a three-way battle between the remaining nominees (one from Blazing Saddles, one from Chinatown, and one from A Woman Under the Influence), with two nominees finished tied for second place, and the winner just a few points ahead.
