Quoted By:
>According to Jones, Schlesinger and the Warner Bros. studio executives were less than pleased when they screened The Dover Boys, and went through the process of attempting to fire him, despite the fact that the studio wanted him to abandon his Disney-like animation (this cartoon might have been seen as going too far to do so).[3] A replacement for Jones could not be easily found due to labor shortages stemming from World War II, so he was kept aboard.
So this whole short was pretty much Jones giving a big fuck you to WB saying "You want humans? Well I'll give you humans"
