The Man Who Wouldn't Die!
Rulah has faced a lot of tough animals in her career as Jungle Goddess. She's even defeated a pack of wolves by hitting them with another wolf. But never - we are promised - has she had occasion to fight a goat. I guess they were running out of cool animals. You can get the whole story at the Comic Book Catacombs.
Burne Hogarth - on the other hand - knew what to do when Tarzan had fought enough lions. Have him fight giant lions! (Lots of other great Tarzan newspaper strips in that link too.)
