This is the first Merrie Melodies cartoon in which a character says "That's all, folks!" at the end. This line had only previously been spoken at the end of Looney Tunes cartoons, while "So long, folks!" had been the closing line for Merrie Melodies cartoons. Either of these two lines would be spoken at the end of Merrie Melodies cartoons released over the next few years, with "That's all, folks!" becoming more frequently used and eventually replacing "So long, folks!"
Included in Warner Home Video's 2006 6-disc DVD release "The Busby Berkeley Collection".
This is the first Merrie Melodies cartoon to feature a new opening theme song, "I Think You're Ducky", written by Charles Tobias, Gerald Marks, and Sidney Clare.
