Agent Cool Blue

I recently purchased a bottle of "Agent Cool Blue", a mouthwash designed for children that helps them brush their teeth (it tints their teeth blue so they will know where to brush). Caleb was excited when he saw my purchase and remarked, "my Nana has Agent Cool Blue. It's blue also but her's is for cleaning the bathtub and toilet". Apparently Caleb thought the blue tinted bathroom cleaner his Nana uses was the same thing I purchased for him!
