(Strip Number 753, Original Publication Date, 26 November 1984)
Panel 1: As our story continues, we find ourselves at Elly's aerobics class. She looks at herself in the mirror and thought-bubbles that she doesn't look that bad this time around.
Panel 2: She tells Connie that she has no idea why it is she looks great one day and horrible the next.
Panel 3: She asks her if it could be an illusion or a psychological trick being played on her.
Panel 4: Connie hints at the real source of trouble by saying that it's all done with mirrors.
Summary: This is because Elly's self-image is somewhat on the variable side. On the rare days that she actually feels good, she sees the rather attractive woman everyone else does. The rest of the time, she sees the fat, pale, ugly, old-before-her-time frump she believes herself to be.
