Professor Tom

Tom pretends to have a cold in order to trick Mammy into letting him stay inside for the night. Jerry tricks Tom by making him think he really is sick - with the measles.

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.

Jerry Mouse befriends a newly hatched duckling who can't swim and ends up protecting him against his feline nemesis, Tom.

Someone drops off three cute little kittens; Tom is put in charge of them while Mammy goes shopping. But behind her back, the three little angels are real devils.

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".

Donald and Mickey are overdue on their rent, so the sheriff is preparing to evict them and sell their belongings. Goofy the ice-man comes by and helps them move out before the sale, but their piano doesn't want to stay on his truck. Meanwhile, Donald has a fight with a plunger and a fishbowl after removing a heater from the gas line.

Jerry and his diapered little mouse friend flood the kitchen, then use the freezer to turn it into a skating rink. Even though Tom finds a pair of ice skates, the mice have no problem outmaneuvering him.

The family dog warns Tom not to make any noise so he can take a nap. Jerry hears this and immediately devises plans to ensure that the dog's nap will be interrupted.

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.

Tom chases Jerry into a bottle of invisible ink, and the now-invisible Jerry proceeds to have fun torturing Tom.

A moment after a bottle of white shoe polish pours on Jerry, Tom hears on the radio that a white mouse, having swallowed an explosive, has escaped from an experimental laboratory and that slightest jar of the mouse could cause it to explode and blow up the entire city. It is then that Tom notices now-white Jerry and concludes it's the escapee.
