Nebraska:
Karen Hough is a long-time practitioner of "equine massage," which supposedly is beneficial in all sorts of ways to the animals in question.
But in Nebraska, you have to be a veterinarian to give a massage to a horse.
What’s worse, under Nebraska state law, she can’t even give out advice on how to massage horses: “They told me I couldn’t give massages for money; I couldn’t do it for free and I couldn’t even tell friends how to do it. That last one really got to me. To me, that is restricting my free speech.” Of course, by using occupational licensing, the board can restrict who gets to massage horses, rubbing out the competition.
(And it doesn't even say there was a happy ending)
