It's the national anthem for Americans.

Answer 4

Originally they were going to brand a large letter M on the forehead of all the morons to make it easier to identify them. However, many people find the idea of branding other human beings a little repulsive so the plan was scrapped. Instead, they gave out cowbells and now the morons identify themselves.

Nothing just entertainment.
