One day Jane met Tarzan in the jungle. She was very attracted to him and, during her questions about his life, she asked him how he managed for sex. "What's that?" he asked. She explained to him what sex was, and he said, "Oh,Tarzan use hole in trunk of tree."
Horrified, she said, "Tarzan you have that all wrong! I will show you how to do it properly." She took off her clothes, lay down on the ground, and spread her legs wide. "Here," she said, pointing, "You must put it in here."
Tarzan removed his loincloth, stepped closer and then gave her an almighty kick in the crotch. Jane rolled around in agony. Eventually she managed to gasp, "Why the hell did you do that?"
