Tom is attacking Jerry with everything that's in the house. He throws vases, paper airplanes, lamps, and anything he can get his hands on to get Jerry. Basically, it's like a war is going on. Jerry retaliates by using a cheese grater, and using fireworks to fight Tom back with. (I.E. Yankee Doodle Mouse) They do the same thing fighting back and forth for the rest of the episode. It ends with Jerry winning the battle, as he blows up Tom using the fireworks, turning him into an American Flag.
