Six Bears and a Clown (1972)

An owner of one circus decides it's better to have trained pigs than trained bears and offers his competitor a swap. As the bears are gone from the circus, clown Cibulka is fired as well. Fortunately children in the town help him to get a job dressed as a woman, Cibulka now works as a school cook, his trained chimpanzee helps him. The bears escape during the transport and on bicycles and motorcycles arrive to the school, where they scare the cleaning lady and the janitor. To cover up for his animal friends Cibulka now has to do these two jobs as well. And a school inspector is coming for a visit today.
