(Newser) – At least one penguin at the St. Louis Zoo appears to be a feisty opponent of Newt Gingrich. The GOP candidate is sporting a bandage on his finger after getting nipped by a small penguin during his tour of the zoo on Friday. Gingrich was in St. Louis to speak during the NRA's annual meeting, and was treated to a behind-the-scenes visit with two Magellanic penguins while at the zoo. One of them nipped Gingrich on the finger. A zoo rep says a small bandage was all the medical care required. (Read more penguin stories.)
