A zoo acquires a rare type of gorilla and is quite happy about the purchase. The gorilla is a female. After a few days it is noticed that the gorilla is irritable and off her feed. After a vet looks at her, it is realized that she is in heat.

The problem is that no male gorilla is available at the zoo or anywhere else.

In weighing the problem, someone realizes that Paul, an employee who sweeps out the cages is reputed to be well enough endowed to satisfy any female. Paul is also not too bright.

Paul is approached and asked if he will make love to the gorilla for $500.

Paul agrees - but on three conditions. 1) I don't have to kiss her 2) I want nothing to do with any offspring of this union.

At this point, Paul hesitates, as if searching for words and also seems embarrassed.

The zoo officials ask: " What's your third condition?"

Paul says: " I need another week to come up with the $500".
