Zookeeper

Two guys own a zoo. To their angst their lone female gorilla goes into heat. Knowing she will be violent if not looked after they take her to a vet for advice. He says she needs to be bred by a male gorilla. Knowing they can't find a male they weigh their options. One says to the other, hey that guy that cleans the cages is kind of crazy, maybe he'll do it. They ask him if he'd do it for $500. He asks for some time to think about it. The next day he comes back to the guys and says he'll do it on three conditions. 1) No commitments, once it's done it's over. 2) If there is any kids I'm not responsible. The two say O.K. no problem, what's your third condition? Well he says it's going to take me a few weeks to come up with the 500 dollars......
