S1·E17 Tarzan and the Rough Rider

The jungle is visited by the former President Teddy Roosevelt and, while on the hunt for animal specimens to study (which Tarzan heavily disapproves of), both are kidnapped by conspirators. In the process of escape, Tarzan teaches the President the importance of respecting nature, and he gains a new appreciation for it by the time he leaves, promising to bring that lesson home to America.
