Apparently, McCartney got the idea for this while he was watching a pair of monkeys conducting business: "I was up on a flat roof meditating and I'd see a troupe of monkeys walking along and the male just hopped onto her back and gave her one, as they say in the vernacular. Within two or three seconds he hopped off again, and looked around as if to say, 'it wasn't me,' and she looked around as if there had been some kind of mild disturbance but thought, huh, I must have imagined it. And I thought, bloody hell, that puts it all into a cocked hat, that's how simple the act of procreation is, this bloody monkey just hopping on and off. There is an urge, they do it, and it's done with. It's that simple." McCartney was in India at the time.
