This cute little fella has had two captions. It was one of the first few Squaredy Cats designed. This one incorporated the style of using a visual that hearkens to a well-known idiom: An apple a day keeps the doctor away. Some people suggested it should be "not squared of needles," so we presented it that way a few times, but we are always pleased when someone "gets it" the way it appeared originally, so we keep it as is.
Take the message a step further, and consider that eating healthy will likely insure you don't have to visit the doctor too often.
