I believe that Rapaire has the right of it. I can hardly imagine that young John Clayton III, Lord Greystoke, with all that English blue blood, would possibly behave in an untoward manner.

Now—John Carter and Dejah Thoris! That was a whole other world!!   CLICKY.

Careful! You don't want to cast asparagus on Tarzan's character and get him all pissed off!   "Go get him, Muffy!!"

Actually, mouse, the "yodel" came from the time Jane had accidentally fallen into a pool of quicksand. Tarzan couldn't get to her without getting trapped himself, so he told her he would take a long vine and swing out over the pool, and that she should reach up and grab the vine as he swung over her.

He grasped the vine, leapt off the tree branch and swung out over the pool of quicksand. Jane made a desperate grab and the yodel was born!

The yodel translated roughly as, "The vine, Jane! I said grab the vine!!!"
