USING THE STREET AS YOUR PERSONAL DUMPSTER IS BIOLOGICALLY DETERMINED, ACCORDING TO STANFORD STUDY

Scientists at the Stanford Genome Laboratory have identified the chromosome responsible for littering behavior in humans. Specifically, a mutated gene on the 17th chromosome, labelled the "Trash Allele" by researchers, causes its carriers to toss fast-food wrappers, cartons, and soda cups out of the open windows of their automobiles. According to team leader Dr. Winston Snyder, this allele combines with several others on adjoining chromosomes 16, 18, and 19 to form the notorious "Asshole Constellation."
