As everyone knows, the only reliable way to distinguish a loathsome Communist infiltrator from a true-blue loyal American is to field-test their knowledge of baseball. It is a scientific, verified fact that Communist brain molecules cannot process information pertaining to the National Pastime-- a phenomenon best exemplified by college southpaw Fidel Castro, whose lamentable Red sympathies resulted in decades of disorientation, mental fugue, tinnitus, and the Presidency of Cuba. Havana insiders have revealed that even today Castro occasionally believes himself to be Marty Pevey, first-base coach for the Toronto Blue Jays.
The Baseball Test has been our most effective means of uncovering Communist spies for many years, but at what point did it first become established in the public consciousness? Was there a specific film or radio show that used this device in a particularly dramatic fashion?
