Farm Implements and Rutabagas in a Landscape Steaminess Rating

Exactly how steamy is this poem?

PG

It's about cartoon characters: how could we not give it a "G" rating? While we wouldn't put it past Ashbery to mix sex and cartoons, he doesn't do so here. And while we don't think Popeye scratching his balls is a particularly pleasant image, we think it bumps the rating to a "PG".
