Do you have what it takes to give a 400-pound lion a physical exam? In Florida, host Jeremy Brandt does the unthinkable: sticking his hand down a lion's throat. After a close encounter with the park's chimpanzees, he gets a once-in-a-lifetime opportunity to perform a neonatal exam on a baby giraffe. Even though it's only one day old, the giraffe is already over 6 feet tall! Next, he tries his hand at goat ranching before boarding a shrimping boat in the Gulf of Mexico.
