Chestnut, "2 Broke Girls"

Poor Chestnut's the sanest character on the show, and he (she?) doesn't get any lines. A horse living in Brooklyn, peering in a doorway or standing patiently in a bleak yard, is not the most plausible sight gag, and we're not sure how many times you can see a horse in leggings before it gets old. But fans were thrilled when Chestnut was finally put to some good plot use in "And the 90s Horse Party," where Max and Caroline charged hipsters to ride a horse. We're just waiting for Chestnut to get his own Twitter account.
