Tarzan And Jane
After living in the jungle for a while Jane wanted to do the nasty with Tarzan and asked if he knew what sex was.
"What's that?" he asked.
She explained to him what sex was and he said, "Oh, Tarzan use a hole in the trunk of tree!"
Horrified, she said, "Tarzan you have it all wrong! I'll show you how to do it properly."
She took off her clothes, dropped to the ground and spread her legs wide.
"Here," she said, "Do to me what you do to the tree"
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, "What the hell did you do that for?"
"Tarzan check for bees first!"
