Three-eyed fish

In a 1990 episode, Bart catches a mutated, three-eyed fish in the local river – a nod to the pollutant effects of the town’s nuclear power plant. Over 20 years later, in 2011, a real-life fish – and practically a dead-ringer for its cartoon counterpart – was discovered in an Argentinian reservoir located near a nuclear facility.

One 1998 episode centered around Homer and Bart’s racket reselling cooking oil – a crime that seems daft on the surface, but was reported as becoming a real life crime caper some 10 years later.
