A woman and her friend are visiting the zoo.
They are standing in front of the big silver
back gorillas cage, when one woman makes a
gesture that the gorilla interprets as an
invitation. He grabs her yanks her over the
fence and takes her to his nest in the pen.
There he ravishhes her and makes passionate
love to her for about 2 hours till he is
tranquilized, and the lady taken to hospital. 

Her friend visits her the next day and asks" 

Are you hurt?" 

She replies. Of Course I'm hurt, He hasn't
called! He hasn't written!
