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 ravishes her and makes passionate love to her
 for about two hours till he is tranquilized, and the lady taken to
 hospital.
 
 Her friend, deeply concerned, visits her the next day. "Are you
 hurt?" she asks.
 
 She replies, "Of course I'm hurt! He hasn't called! He hasn't
 called, he hasn't written!"
