Boop-Oop-a-Doop is an animated short film created by Fleischer Studios and released on January 16, 1932, which is part of the Talkartoon series.
[2] The film begins with a giant Betty Boop flag which flies over a circus big top.
As Betty returns to her tent, the ringmaster follows her inside and sensually massages her legs, surrounds her and threatens her job if she does not submit.
He leaps in to save Betty's virtue, struggling with the ringmaster who loads him into a cannon, firing it, and, thinking that he has sent the hero away, laughing with self-satisfaction.
Koko is hiding inside the cannon, and strikes the ringmaster out cold with a mallet, returning with "the last laugh".
