The old janitor shuffled over. "What?"
"I need to ask you a big favour."
"I'm busy raking up the leaves," replied the old man, turning to go.
"It's worth 2000 dollars."
"Oh?"
"Yes, it's the female gorilla: Maisie. She's in heat, but I can't find a mate for her, and she's becoming increasingly agitated."
"I don't know any gorillas, mate."
I smiled at the joke. "No, I wondered if you would mind having sex with her."
"For 2000 dollars?"
I nodded.
The janitor scratched his grey stubble for a moment, and then replied, "OK, but under three conditions."
"Yes?"
"Yes. First: no one must know."
"OK."
"Second: I won't kiss the beast."
"Sure. And third?"
"I need a bit of time to get the money together."
