The zoo-keeper traversed the country looking for a suitable mate for his gorilla but couldn't find one. He hit upon a novel idea and went to his local pub and inquired from the landlord if he knew of a big man who would serviced a gorilla for a fee.
The landlord of the pub pointed out Murphy, the hefty Irish navvy, who would do anything for a fee.
The zoo-keeper and Murphy agreed to do the job if three conditions are adhered to:-
1) There will be no abortions
2) She will not hug him
3) All the siblings are brought up as Catholics
