Monkey sex

Apparent wildlife lover Clementine Ford attaches the following quote to a crotch-shot of a male monkey:

Sure, there are monkeys with bigger balls out there. But it’s not the size that matters, right? It’s what inside that counts. And I’ve got 15 kids, so I’d say what’s inside these bad boys is pretty, pretty, pretty, pretty good.

I’m confused: who’s she quoting?
