One member of the Sycamore family makes fireworks in the basement. One has a printing press in the parlor. One practices ballet all the time without getting any better. One writes bad plays that no one ever reads. The tax collector is told by the family patriarch that he hasn’t paid his taxes for years because he doesn’t believe in the income tax. The story reaches a comic climax when an upper-class couple comes to dinner on the wrong night and is assailed by all the mayhem. But if the Sycamore family is mad, it becomes clear that the rest of the world is madder.
