Merrie Melodies - Boyhood Daze (1957)

Boyhood Daze is a 1957 Merrie Melodies short directed by Chuck Jones.
Censorship:
When this cartoon aired on ABC, the following scenes were cut:
The pre-credits scene of Ralph breaking the window and sadly going upstairs to his room (The Bugs Bunny and Tweety Show provided their own opening and closing title cards for the shorts they aired and cut out any opening credits that played over moving scenes).
The entire sequence of Ralph's parents getting captured by African jungle natives and Ralph swooping in to rescue them by slaughtering the natives.
In contrast to ABC, versions shown on TBS and Nickelodeon left in the pre-credits scene and showed the entire sequence of Ralph rescuing his parents from jungle natives, but cut the initial shot of them dancing around the cauldron, where their shadows are cast over Ralph's parents as they talk to each other and where they back away and run as Ralph advances on them were left in.
Cartoon Network left in the African native fantasy the pre-credits sequence, but edited the scene of Ralph imagining himself as a convict awaiting punishment from the warden in his cell to remove Ralph smoking and stomping out a cigarette.
