4. In the Delta region of Mississippi, Kool-Aid pickles have become ridiculously popular with kids. The recipe's simple: take some dill pickles, cut them in half, and then soak them in super strong Kool-Aid for more than a week.

9. Speaking of people who get credit for discovering America, when he wasn't drawing maps and trying to steal Columbus' thunder, Amerigo Vespucci was a well-known pickle-merchant.

11. During the 1893 Chicago World's Fair, H. J. Heinz used pick-shaped pins to lure customers to his out of the way booth. By the end of the fair, he'd given out lots of free food, and over 1,000,000 pickle pins.
