Keepers at a zoo realized that a lone female gorilla that was recently brought in for habitation was badly in heat.

Because of this the gorilla was acting very amorous with the keepers every time they tried to feed her. So they figured if she just had sex that she might calm down.

It was then they approached a rather dumb janitor and asked him if he'd like to have sex with the gorilla for $500.

The janitor laid down three ground rules.

1: He didn't wanna have to kiss her.

2: He'd like her to be freshly washed.

And 3: He'd need another week to come up with the $500.
