(Strip Number 5086, Original Publication Date, 4 February 1989)
Panel 1: As they get ready for bed that night, Elly ruefully states that like most kids, Liz has just gone through a phase of thinking she's ugly.
Panel 2: As she brushes her teeth, an off-camera John tempts fate by thanking goodness that people eventually mature to a point where they can accept themselves and be objective about their looks.
Panel 3: Elly pauses to stare at something 'horrifying' in the mirror.
Panel 4: John is horrified because a freaked-out Elly asks him if he thinks she's got one eye higher than the other.
Summary: John is, of course, as screwed here as he was when Liz asked why her nose was too something. He can't answer that question in a way that won't get him in trouble. As for Elly herself, Liz's insecurity cannot be said to have anything to do with how she was raised but instead must be blamed on an external evil such as network television or peer pressure.
