One day, Tarzan is swinging through the jungle on his favourite vine when he crashes into a monkey swinging in the other direction.

They both land safely on a tree limb below, but when Tarzan looks up, there is only one vine hanging above them. Next to it, there is only a very thin branch.

“Were you swinging on that thing?” asks Tarzan.

“Yes,” replies the monkey.

Tarzan is amazed. “How do you do that?”

The monkey rolls his eyes. “Am I the only one in this whole jungle who knows how to drive a stick?”
