I remember as a kid in the 1950s, Marlon Perkins was then director of the St Louis zoo and had a live show on TV. He once was going to demonstrate how to milk a rattlesnake but instead showed the viewing audience first aid for a rattlesnake bite.
Marlon Perkins: “I’ll stay in the boat and monitor the instruments while Jim hops into the swamp to give the alligator an enema”!
