Naughty Neighbors

Naughty Neighbors is a 1939 Looney Tunes cartoon featuring Porky Pig.

Plot
Porky and Petunia are heads of the rival Martin and McCoy clans. A Kentucky hillbilly feud between the two rival families ends with the love that Porky and Petunia discover for each other. An uneasy peace follows as the families attempt to emulate their offspring, but soon, trouble breaks out once more. To resolve the situation forever, Porky has developed a special grenade, called a feud pacifier, which transforms and domesticates all of the mountain folk. The hillbillies are depicted as cross-eyed, smiling, goony animals.
