Probably an old one but.......
When Jane initially met Tarzan of 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, "Oh,...Tarzan use hole in trunk of tree."

Horrified, she said, "Tarzan you have it all wrong,...but I
will show you how to do it properly." She took off her
clothing and laid down on the ground. "Here" she said, "you
must put it in here."

Tarzan removed his loincloth showing Jane his considerable
manhood, stepped closer, and then gave her a mighty kick
right 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."

 

hahahahaha.......
