Ew nasty

On the wall in the stairwell near my room, there's a poster that has a list of ways to get healthy or stay healthy or something. One of them was "eat the peel on apples" but they had a picture of a banana next to it. Even though I read apple I was thinking banana because that's what the picture is of. I had to do a double take on that one because who eats the peel on bananas?
