I found these great illustrations in an old issue of Print magazine. It was the August 2009 issue. I thought these were so much fun, and they reminded me of Aqua Teen Hunger Force on Adult Swim. Although the foods on the left are better for you, I LOVE the illustrations of the "bad" food on the right!
These are the "Fitwits" on the left and the "Nitwits" on the right. The illustrations are done by Nathan Mazur and appear on character cards that "list their relatable, human qualities on the back. Bling Bling, the name given to a carton of milk, has positive hobbies, for instance, including 'Girls at Recess' and baseball."
