A professor at the University of Georgia performed a study on why people put Darwin fish on their cars. He found cars in parking lots that have the fish and left surveys under their windshield wipers. He received back a wide range of responses: Some people did it as a joke, some did it to spite Christians, and others just wanted to state their beliefs, not intending to insult anyone.

I would put a Darwin fish on my car except I don\’t want to come back to a windshield covered with Jesus pamphlets.
