Yip Yip Yippy
Yip Yip Yippy is a 1939 Fleischer Studios animated short film. The short was the final official Betty Boop cartoon in the Paramount Picture series. Although this was billed as a Max Fleischer cartoon/a Betty Boop cartoon, Betty Boop herself did not appear. Despite her non-appearance, this is the last official Betty Boop cartoon in the Paramount series. Premise. A drugstore cowboy reads a dime novel and imagines himself as an Old West cowboy battling a cattle rustler.
