They used mechanised goats, so in effect you're both right.

Mind, if you'd ever seen one of the cybernetic abominations you'd never eat a Pringle chip again. I grew up with cyborg hamsters (my Uncle Bertrand was always tinkering with rodents and computers), so I'm used to such creatures, but I should imagine they'd be pretty off-putting to the average consumer of potato crisps.

That's why they have to keep their goats in secret bunkers located deep in the heart of the Rocky Mountains, and destroy all photographic evidence that comes to light.

I love Pringles, though, goats or no goats. Their Pale Ale and Pickled Onion flavour chips are the best thing since sliced bread reformed potato pieces.
