  1. All right, Riley, just WTH is a “Grenn-winged” duck? Don’t you mean Green-winged? And for that matter, it should be a teal, not a duck. This is based on my being a long-time waterfowl hunter, plus a quick internet search for verification.

  2. light-side. You can tell because they were all diagnosed by their quacks.
