"Tarzan check for squirrels." joke

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.

Whats 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 it all wrong! I will show you how to do it properly.

She took off her clothes laid down on the ground and spread her legs.
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
What the hell did you do that for?
