Synopsis for "The Escape of... Monsteroso!"
An alien child accidentally presses the escape pod button of his parent's spacecraft while in the vicinity of Earth and is thrown from the wreckage and rendered unconscious in an African jungle. An American circus owner hears of native reports of a crashed ship, goes to investigate, and discovers the creature whom he mistakenly assumes to be dead. He forgets about displaying the monstrous being in his circus and instead delivers him to a museum whereupon he regains consciousness. The startled creature wanders New York City for a while, until hounded by the military and their tear gas shells, climbs up the side of the UN building. They shoot him with a tranquillizer dart which makes him fall into the river. His parents eventually arrive and recover their child. They state "It is fortunate he is unharmed. Fortunate...FOR YOU." and leave Earth.

Upon receiving the Outstanding Scientific Achievement of the Year award, Henry Fletcher confides in the janitor, Tom Smith, of his next theory: that there is a higher power of some sort guiding the human race to its greatest achievements.

Synopsis for "The Joker!"
Victims of a man's practical jokes get together with the idea of dressing up as Martians to kidnap the prankster, but unknown to them, he is outside the window listening to their plans. When horrible alien creatures later show up, the joker calmly allows himself to be blindfolded and taken to their spaceship. He makes causal banter along the way and thinks they must be disappointed their gag did not work. The creatures reply that he is not reacting the way they thought their first capture for their zoo would respond. When the blindfold is removed, and Mars is rapidly approaching through the viewscreen of the spaceship, the distraught joker utters "All I've got to say is that this is taking a joke too far!"
