My niece had a beautiful sweet-natured Golden Palomino many years ago appropriately named "Goldie" that even I (who spent most of my life admiring but terrified by horses) could ride with ease.
My niece would enter horse shows as a child and get extra points for keeping Goldie "under control" while the other horses were skittering around, nipping at each other, etc. What the judges didn't know was that Goldie's favorite state was "standing still" and she was an Olympic Gold Medalist at "standing still". If there was an Olympic event for eating, she'd have taken gold in that one, too.
Goldie liked to flap her lips and stand around with what looked like a two-foot tongue hanging out of the side of her mouth. She looked like such a doofus, you had to laugh at her. She was spotted by a "horse talent agent" and went on to be one of the Mr. Ed's in the Mr. Ed show at Universal Studios Orlando. Yes, shocking as it seems, *Mr* Ed was sometimes *Ms* Ed. She was trained to flap her lips on cue, so it looked like she was "talking". Later she moved on to a riding stable, where she helped many children get over their fear of horses, like she did for me.
