Bending the rules: People sending their children through the U.S. Postal Service; a Sikh man in the early 1900s tries to use the Supreme Court's racist rulings to his benefit; and the little-known story behind the iconic folk song "Rock Island Line."

Squabbles big and small: A dining room turns two besties into lifelong enemies; a researcher embraces the panda craze; and why some dinosaur skulls were built to take a beating.

A quick update from Tony about the show.

Tales of deception and trickery: A sneaky orchid seeks sexually frustrated pollinator; a battle fought by decoys; and a gender-bending zombie invasion of the Chesapeake Bay.

The payoff is all in the delivery: Sending mail via cruise missile; preparing a strong-willed orangutan for primate parenthood; and failing to land a joke from the "gag file" of Phyllis Diller.

Technology's grip on us: The 4-1-1 on what's behind your selfie; an artist's computer simulation shows humans aren't as unique as we think; and how the invention of standardized time made America tick.
