Larry spends this episode going to extremes to show you how Americans go to extremes when it comes to animals. He begins in the coastal marshes of Florida where he's assisting a guy with the ultimate alligator obsession. Larry helps the young researcher take blood, urine and even vomit from gators in the name of science. Then we are off to Colorado, where a terrified Larry works with the brave, dedicated staff of Serenity Springs, a haven that takes in ferocious big felines that have nowhere else to go and gives them state-of-the-art medical and dental care. Finally, Larry apprentices with a Maryland taxidermist, revealing how Americans turned stuffing critters into a popular--and sometimes very wacky--art form.
