Puny God talked and screamed a lot, and very loudly. Like a little baby whose parents wouldn't buy them the new toy they wanted. Hulk was annoyed. Hulk also didn't like Puny God wearing green. Green was Hulk's color. And Puny God had thrown Tony out of a window. Hulk liked Tony. That was the final straw.
Hulk's favorite thing to do was smash. Hulk smashed windows, cars, and buildings. But Hulk had more fun smashing Puny God than smashing anything else ever before.
Hulk liked the new look of Tony's floor. And Puny God wasn't talking anymore.
