***New in update*** - new funny mouths - smooth image transition Ever wondered how you'd look with a piercing? With braces? Or a mustache? Ever asked yourself if the famous Salvador Dal sofa would go with your eyes? Wait no more. This app features a collection of photos featuring human and animal mouths in different moods that will make your friends laugh. Of course do not forget to get someone to take a picture of you and your favorite funny mouth. Using the app: select the photo and hold the iPhone/iPod Touch over your mouth with the screen facing away from you. Slide with your finger to change them.
