A zoo had acquired a rare species of gorilla but although the female was in season, they had no male gorilla to mate with her. In desperation they asked one of the keepers whether he would be willing to have sex with the gorilla for a hundred dollars. The keeper asked for a little time to think about the idea.
The following morning, he went back to the zoo bosses with his answer. ‘I’ll agree to have sex with the gorilla,’ he said, ‘but on three conditions. First, I don’t want to have to kiss her. Second, I want nothing to do with any offspring that may result from this union.’
‘Yes, that’s all fine,’ said the zoo bosses. ‘What is your third condition?’
The keeper said: ‘You’ll have to give me another week to come up with the a hundred bucks.’
