Two gay guys are at the Zoo. They come across a gorilla and notice that the male gorilla has a massive erection. The gay men are fascinated by this.
One of the men just can't bear it any longer, and he reaches into the cage to touch it. The gorilla grabs him, drags him into the cage and mates with him for two hours non-stop, while the zoo attendants helplessly stand by. When he's done, the gorilla throws the man out of the cage.
An ambulance is called and the man is taken away to the hospital.
A few days later, his friend visits him in the hospital and asks, "Are you hurt?"
"AM I HURT?" he shouts. "Wouldn't you be? He hasn't called! He hasn't written!"
