Mousey little Prof. Calvin Q. Calculus introduces his latest invention, the “portable hole.” It changes the world, and much of the cartoon shows examples of its many uses and abuses. A criminal steals it for evil purposes. The professor’s wonderful invention fails to impress his horrible, nagging wife, though. She endlessly browbeats and insults him about everything. Eventually, the man calmly creates a hole, places it underneath his wife as she continues to tell him just how worthless he and his inventions are, and allows her to fall through the hole and into the Earth’s crust. Moments later, the wife is chucked back up the hole, and a distraught devil climbs out and says, “Don’t you think I have enough problems down there without her?”
