Bosko, the very first Looney Tunes star, appeared in Warner Bros. cartoons from 1930 to 1933, when his creators moved to MGM (they continued making cartoons featuring him until 1938, after which he faded into obscurity). "The Booze Hangs High" was one outing for the high-voiced character, showing him dancing around with some farm animals and playing them like musical instruments. The menagerie includes some inebriated pigs (and this cartoon got released during Prohibition!).
Drunkenness is quite often a source of humor. Cartoons occasionally depict a besotted stork delivering babies. "The Andy Griffith Show" had Otis. It seems like it's only been during the past twenty years (approximately) that alcoholism became socially unacceptable. I assume that most people would consider it such, despite its continued existence.
Anyway, this is an OK cartoon, despite the limited plot line.
