As shown in the new Netflix documentary
Behind the Curve, there is a modern "flat earth movement" that is convinced that they cannot trust science, so they have to do their own experiments to determine that the earth is flat as they feel is illustrated by the 1998 movie
The Truman Show and by the UN flag. Thus, they feel compelled to spend fortunes in trying to prove their flat earth geological model, which all end up inadvertently proving that the earth is round, a globe after all. One poor soul even spent $20,000 on a laser gyroscope to prove the earth is flat, only to have it prove the globe geological model. This is tragically hilarious. Tragic for spending fortunes instead of keeping it in the family, and hilarious in that all of their flat earth arguments are as useful as flat tires. However, if any of them need psychiatric attention, then it's not funny. What is funny is the epic irony.
