Part Time Pal (1947)

The popular cartoon cat and mouse are thrown into a feature film. The story has the twosome trying to help an orphan girl who is being berated and exploited by a greedy guardian.

Tom invites Toots to an elegant dinner. However, he's made the mistake of trying to put Jerry to work, as a serving boy, a corkscrew, and other tasks. Jerry puts up with a little of this, but mostly gets revenge on Tom.

Jerry crashes a vase onto Tom's head, which gets Mammy to throw Tom out. Jerry at first revels in his freedom, but soon tires of this, and, under a flag of truce, hatches a plan with Tom.

Jasper is given an ultimatum by his master: break one more thing and you're out. Rodent Jerry does his best to make sure that his tormentor "gets the boot".

Minnie gives Figaro a bath and ties a ribbon around his neck. Figaro feels like a sissy, and when he mixes it up with some alley cats, they mock him, and the leader attacks. But Figaro is so afraid that his shaking topples a series of trash cans onto the aggressor. The rest of the cats didn't see this happen, and think Figaro defeated their leader. Of course, now he's all dirty, and he needs another bath.

Tom's new book on "how to catch a mouse" doesn't prove too helpful against Jerry; actually, Jerry seems to make better use of it than Tom.

Professor Jerry teaches a course in how to outwit cats, but his pupil seems to know more than Jerry.

Mammy Two-Shoes tells Tom and Butch that the cat who gets rid of the icebox-raiding, breadbox-invading mouse (Jerry) is the one who can stay.

Tom has been out late carousing with his chums. When he gets home, Mammy won't take any excuses, and insists he stay awake; Jerry, overhearing, thus tries a number of schemes to get Tom to sleep.

Tom, sick of Jerry stealing the milk out of his bowl, poisons it. Instead of killing the mouse, the potion transforms him into a muscular beast.
