"Soda Jerks" is a very strange cartoon for two reasons. One is that although it's a very old cartoon, the copy I found was in color, as decades later, someone decided to color in this black & white cartoon...and they did it by hand, not using computers. Oddly, they colored the police uniforms green! Another is the plot....which is just plain weird!!
Mutt and Jeff are working as soda jerks in a drug store. Mutt is treating Jeff badly, ordering him about, so Jeff tries to get even by spiking the syrup with some sort of pep tonic. The results on the customers is like crack cocaine...and the folks start dancing about and assaulting cops! What's next? See this weird film if you like...or not.
The cartoon is probably one you won't see on TV because it's a bit archaic AND it sends a confusing message about drugs....mostly that they are cool and help you beat up cops! Truly odd but watchable...but the bongo music they added later is pretty annoying and strange.
