This photo of my poor family and friends was taken by my niece Chelsa at one of our yearly family campouts.  Most of the distortions were made with the versatile Stretch Tool.  Depending on the setting of the Stretch Area Affected parameter, Stretch manipulations can vary from a fine adjustment on a small face to a gross contortion of the entire image.  Shrink, Grow and Twist effects have also been applied.  See if you can figure out which people have been warped.
