Mammy-Two-Shoes (not dubbed by the PC-brigade in the version I saw) has just finished cleaning the whole house when Tom bursts in the door, covered in muck, chasing Jerry. She freaks and tells him to keep the house spic and span until she gets back from the store. This he has no problem doing, but Jerry, for no other reason than to be mean, decides to wreck the place so Tom works himself to death picking it up after him.
There are some good gags but I'm surprised no one complained at the final bit where Tom, covered in coal dust (now looking like a black cat) pretends to be some other cat to Mammy-Two-Shoes and acts like a retarded, cotton-picking 19th century slave. I don't find it offensive, he's probably just mimicking Jim from Huckleberry Finn but it's this kind of thing that cartoons got away with back in the day and something you'll never see in the airbrushed, static, PC crap of today.
No one is credited for Tom's voice or Mammy-Two-Shoes'.
