As you may know, cartoonist and children's book illustrator Mo Willems is trying to become a radio cartoonist. We've asked you to caption some of his drawings and we've received hundreds of submissions. So with your help it's been a pretty funny endeavor.

Also at the Monkey See blog, we have a fresh batch of four captionless cartoons for you to add your humor to.
