In "The British Invasion", Jane's three friends from England come to see her and they get into a rather bad situation, leading to Jane showing just how much she has changed from a prim and proper Victorian lady.
Eleanor: First you put us onto a log and send us down the river. Next you strip us to our unmentionables and shove us into the muck. What's next? Will you have us hoot like gorillas and swing from the tree tops?
Jane: If it keeps us alive! In case you haven't noticed, ladies, this is the jungle. It's not a garden party and I never should have pretended it was.
Tarzan and Kats (one of the Leopard Men) tag-teaming in "The Leopard Men Rebellion".
Terk getting a pack of raptors from Pellucidar to back off after she and Tarzan had returned one of their own who'd been lost on the surface in "The Beast From Below", it's a long story. The normally fearless (and vicious) dinosaurs not only stop there attack to listen, but eventually do walk away without any further fuss.
The aerial dogfight between RobertCanler and Nigel Taylor in "The Flying Ace".
Jane, who had been getting constantly harangued and insulted by Terk for not being fit enough for Jungle Life in The Race Against Time, snapping back at Terk for her insults and bungee jump off a waterfall to get a flower that will save Tarzan's life.
Jane: The high road ends right here! Listen, you can like me or dislike me. I couldn't care a wit right now. But unless we get that flower, Tarzan is going to die! So kindly close your mouth and hold that vine!
At the end, Tarzan is being choked by Rom. How does he solve this? He uses a mating call to lure crocodiles after them, and breaks the Rosary.
Tarzan: Mating call.
George Williams has spent time in the wild but has nowhere near the endurance or agility of Tarzan and the African tribal people. Nonetheless, he manages to keep up with them, even if he is exhausted by the end. When it comes time to make a seemingly insane jump off a cliff into some trees, Williams goes for it after a little hesitation and actually manages to land without seriously injuring himself.
