Two ladies are walking through a zoo. They come across the gorillas, and after a while they notice that the male gorilla has a massive erection.
The ladies are fascinated by this. Finally, one of the women just can't bear it any longer and she reaches into the cage to touch it. Suddenly, the gorilla grabs her, drags her into the cage and mates with her for six hours non-stop!
When he's done, the gorilla throws the woman back out of the cage. An ambulance is called and the woman is taken away to the hospital. A few days later her friend visits her and asks: "Are you hurt?"
