Tarzan grows up among the apes with no human contact. He cannot contain his lust so he takes to making love to any hole in a tree he can find.

Jane visits the jungle and attracts Tarzan away from the tree holes.

They fall in love and upon the beginning of their consummation of that love, Tarzan lets fly with the kick between Jane's legs.

He explains to Jane as she is withering in pain on the jungle bed-- "I have always had to check for squirrels before and did not think you would mind if I kept to my old habits!"
