"Insanity’s Foible" is about a man who wakes up in a mental ward and ends up meeting some quite peculiar patients.
At the hospital, he entertains himself by laughing at them and causing mischief to pass the time.
As he interacts with his new insane acquaintances and odd doctors, a psychology student-turned-patient shows romantic interest in him, and the man starts to question whether he belongs there, and to contemplate the deeper reasons that landed him in the mental ward.
