One day Jane sees Tarzan swinging on a vine in the jungle. She's attracted to him and asks how he manages to have sex.

"What's that?" he asks.

She explains to him what sex is, and he says, "Oh, Tarzan use hole in trunk of tree." Horrified, she says, "Tarzan, you have it all wrong! I will show you how to do it right." She takes off her clothes, lies down on the ground, and spreads her legs. "Here, " she says, pointing."You must put it in here." Tarzan removes his loincloth, takes a step closer, and then kicks her hard in the crotch. Jane curls up and starts rolling around in agony.

"What the hell did you do that for?" she manages to gasp. "Tarzan check for squirrels."
