What Could Have Been: According to historian Michael Barrier, this short was originally meant to be included on Looney Tunes Golden Collection Vol. 6, complete with an audio commentary from him, but the negatives were in really rough shape and needed more restoration than initially thought, which caused it to be dropped from the collection. Fortunately, it finally saw a re-release as part of the "Essential Daffy Duck" DVD set.
