One of Eiichirô Oda's favorite Tom and Jerry cartoons and the one that inspired him to make Luffy's Gear Three attack.
Working titles for this particular cartoon included "City Cousin" and "Muscles Mouse" before settling for "Jerry's Cousin".
The cuckoo clock gag would appear in the Flintstones episode "A Haunted House is Not a Home", albeit a bit differently. Both shorts are Hannah Barbera productions.
The cat gang concept would reappear (in a friendlier version) a decade later in the Hanna-Barbera series "Top Cat."
This was one of the two Hanna Barbera cartoons to use the Gene Deitch theme, the other was "His Mouse Friday".
