A zoo had among its animals a female gorilla, whose mood was becoming increasingly difficult. The vet concluded that she was on heat and that a mate should be found. The vet contacted some other nearby zoos to find a partner for the broody female, but to no avail. The female gorilla's behaviour continued to worsen, but the vet noticed that she grew calmer, and strangely responsive, whenever a particularly well-built and none-too-handsome keeper entered the enclosure. Being an unprincipled and adventurous fellow, the vet put an outrageous proposition to the keeper: For a fee of five hundred pounds would the keeper "spend the night' with the gorilla, purely in the interests of research of course?....
The keeper, also an unprincipled and adventurous fellow, pondered the suggestion, and after a few minutes agreed to the offer, subject to three conditions. The vet, intrigued, listened to the keeper's demands:
"First," the keeper said, "No kissing."
"Fine," said the vet.
"Second, no-one must ever know - if this gets out I'll kill you."
"You have my word," said the vet, "And your final condition?"
"It's just," said the keeper a little awkwardly, "Can I have a couple of weeks to raise the five hundred quid?"
