First Looney Tunes cartoon to use "The Merry Go Round Broke Down" theme music.
This was the first cartoon to end with Porky breaking out of the Looney Tunes drum saying his trademark line "Th-Th-Th-That's All Folks!".
The pushy puppy does a perfect imitation of Porky, right down to his stutter.
Porky is inspired by a book written by 'Clawed Meatty' - a play on Clyde Beatty, a famous animal trainer of the early to mid 1900s.
