Gorilla Proposition

A Sydney Wild Animal Park had acquired a very rare species of gorilla.  
Within a few weeks, the female gorilla became very 
horny, and difficult to handle. Upon examination, the park veterinarian  
determined the problem. The gorilla was on heat. To make matters worse,  
there were no male gorillas of the species available. 
While reflecting on their problem, the park management noticed Ed, a part  
time intern, responsible for cleaning the animals' cages. Ed had little  
sense, but possessed ample ability to satisfy a female of ANY 
species. So,the park administrators thought they might have a solution. Ed 
was approached with a proposition.  Would he be willing to have sex with 
the gorilla for $500? 
Ed showed some interest, but said he would have to think the matter 
over carefully.  The following day, Ed announced that he would accept 
their offer, but only under three conditions. 

"First," he said, "I don't want to have to kiss her." 

"Secondly, you must never tell anyone about this." The parkadministration  
quickly agreed to these conditions, so they asked 
what was his third condition. 

"Well," said Ed, "You gotta give me another week to come up 
with the $500."
