1) Throughout the film, Elmer is reading a
Bugs Bunny/
Porky Pig comic book.
2) A. Flea's repeated song was covered by Green Day (with drummer Tre Cool singing the song which contains some slight lyric changes).
3) The voice of A. Flea is uncredited and was provided by
Sara Berner, except for the character screaming "T-Bone!" which was done by
Mel Blanc. Blanc also performs the voice of the dog. As usual,
Arthur Q. Bryan is the voice of Elmer.
4) After the flea's pile of dynamite goes off, the dog scampers around the room on his hindquarters, barking in pain, until he stops sharply in mid-run, looks at the audience and says, "Hey, I'd better cut this out, I may get to like it!", then resumes. This gag was deliberately written to see if it would be removed by the Hays Office. Surprisingly, it remained in the cartoon unedited.
5) There is one brief moment on the cover of Elmer's comic book when Porky's mouth is opened and closed.
6) A. Flea would make another appearance in 1947's
A Horse Fly Fleas, directed by
Robert McKimson, in which the "A" in the flea's name is revealed to stand for "Anthony".
7) In the 1995 Turner "dubbed version" (and presumably other TV prints), Elmer's shirt appeared greenish (similar to the shirt color of his prototype Egghead). The restored version on DVD shows that the shirt was originally blue.
7) On a
Cartoon Festivals VHS, this cartoon has the 1939-1940 Merrie Melodies opening music playing over the 1947-1948 WB opening shield and Blue Ribbon titles plastered over the original opening rings, like the tape series' a.a.p print of "
Daffy Doodles".
