When Jane initially met Tarzan in the jungle, she was attracted to
Him, and during her questions about his life, she asked him how
He had sex.

"Tarzan not know sex," he replied.

Jane explained to him what sex was.

Tarzan said "Tarzan use knot hole in trunk of tree."

Horrified, Jane said, "Tarzan you have it all wrong, but I will
Show you how to do it properly."

She took off her clothing and lay down on the ground..

"Here," she said, pointing to her privates, "you must put it in here."

Tarzan removed his loin cloth, showing Jane his considerable
Manhood, stepped closer to her and kicked her in the crotch!

Jane rolled around in agony for what seemed like an eternity.

Eventually she managed to gasp for air and screamed,
"What did you do that for?"

Tarzan replied, "Check for squirrel"
