Expanding on PARDON MY BERTH MARKS, which I just re-watched.
* A who's who of Columbia supporting players circa 1940: Dent, Appleby, Boniface, Laughton, Fiske, Tyrell, Schindell, Toones, Jamison, Eva McKenzie, and Lynton Brent. It feels like one big family reunion.
* Some of the highlights of the train scenes - Buster talking to his bird while the other passengers think he's talking to Mary Christman (Buster saying "you bad girl" seems pretty risque for 1940)
* The cleverness of the Mary Christman/Happy New Year lines.
* Everyone sticking their head out and singing the wedding march song at Buster.
* Fred Toones shaking his finger at Buster when he pokes his head through the curtain.
A definite classic in my book.
