The Bullwinkle Show - Season 2 Episode 212

Once upon a time, there was an evil ugly witch who cast a spell on anything beautiful. In the country one day, she came upon a beautiful Princess and turned her into a horse, figuring that a Prince would not kiss a horse. After six months, a Prince finally passed by and commented that she is a real runner, and entered her into the big race. At the race, Beauty would destroy the field but stopped five feet from the finish line, so he took her to Merlin the Wizard. Several days later, he came back, saying that she has a kiss complex, so at the next race, he kissed her and she turned back into a beautiful woman and they lived UNHAPPILY ever after, because she was still an old nag.
