Synopsis:
Batman begins behaving strangely by spending large sums of money on failing businesses. Superman acts secretly to make the companies profitably to save Batman from embarassment. However, Batman wants the businesses to fail in order to complete the conditions of the will of the late Carl Verrill. When Superman is finally filled in on the scheme, he sells Batman a million dollars worth of worthless trophies, successfully completing the conditions of the will and ensuring that the rightful heir receives the remaining portion of Verrill’s fortune.
