I think guinea pigs are fabulous!!

We were the guinea pigs.

From the very beginning, there was not the slightest doubt that Olga da Polga was the sort of guinea pig who would go places.

It was a classic grand mal seizure. We're all guinea pigs of vaccines.

We're all of us guinea pigs in the laboratory of God. Humanity is just a work in progress.

Guinea pigs are quite difficult to draw, I think, because they're so furry.
