"Although Grandpa hits on the blonde next door, he does it with such charm and perkiness that Brennan gets away with playing what is essentially a dirty old man part. It is worth watching the movie to see him dance with his blonde pickup, clicking his heels, and then sitting her down at a table and showing her his $32,000 bank account--actually just a little notebook, although he claims to have the money (which turns out to be Confederate currency) hidden under his bed. When his date rejects his advances, he says, "The night is young. Why don't you be like the night?" When she pleads to be taken home and is willing do anything he wants in return, he says, "Then what's the use of going home?" But of course his role dictates that he resign himself to playing the grouchy guy who drives her home. Brennan's lines came from one of Hollywood's greatest screenwriters, Herman Mankiewicz, who wrote Citizen Kane."
