Two retired English officers were sitting in their armchairs in a London club reading their respective newspapers.
"By jove," said one, looking over the top of the Times, "do you remember old Carruthers during the war? I thought he'd died, but it turns out they've found him after fourty years living up a tree with a gorilla."
"I say. Male or Female gorilla?"
"Female of course. Nothing queer about old Carruthers."
