First appearance of Beaky Buzzard.
The comic "yoy-yoy-yoy" sound of Beaky's bouncing Adam's Apple was produced with a trombone.
The scene in which Bugs believes part of his body to be skeletal is a reference to Harold Lloyd's execution of the exact same joke in The Freshman (1925).
Beaky Buzzard's voice and mannerisms are modeled after radio character and ventriloquist dummy Mortimer Snerd, created by Edgar Bergen. Because of this, he was originally given the informal name of 'Snerd Bird' before he acquired the name of Beaky Buzzard.
The dialogue "Why don't we do this more often?/You mean just what we're doing tonight?" are the lyrics of a 1941 song, "Why Don't We Do This More Often?"
