Two gay men are walking through a zoo.

Two gay men are walking through a zoo. They come across the gorilla and
notice that the male gorilla has a MASSIVE erection. The gay men are
fascinated by this, whereby one of the men, who just can't bear it any
longer, reaches into the cage to touch it. Immediately, the gorilla grabs
him, drags him into the cage and mates with him for six hours, non-stop,
while the zoo attendants helplessly stand by. When the gorilla has
finished its rodgering, it 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....'
