Before the popular cat and mouse pair Tom and Jerry, there was the Van Beuren's cartoons of Tom and Jerry. At those cartoons, two guys starred a series of bizarre adventures paying plumbers, musicians, fishers, etc., with a similar style of the one developed of Fleischer Studios.

According to Wikipedia, 26 episodes were made, and 11 of them are available on-line, almost all made in 1932. Some of them are presented as "Dick and Larry" cartoon and I found the answer of it at Don Markstein's Toonopedia: Its cartoons were briefly brought back into commercially viability in the early days of television, when everything was in black and white. Since there was already a Tom & Jerry, they were re-dubbed Dick and Larry. As color came in, they faded into complete obscurity.
