(Strip Number 6166, Original Publication Date, 31 January 1988)
Panel 1: We start things off with Phil and Georgia coming for a visit; as Mike points this out, Lizzie sets things in motion by saying that he's brought his video stuff.
Panel 2: Elly warns us what the punchline will be when she freaks out just a little when she says "His 'video stuff'?"
Panel 3: Having taken a bit of a home movie of the Pattersons with his camcorder, Phil asks them if they're ready to see themselves on the tube.
Panel 4: We get a huge whiff of Lynn's crippling self-loathing when Elly looks at herself on the screen and asks "IS THAT ME?!" because she looks at the average-looking woman with a bit of a slouching problem she actually is and sees Jabba The Hutt.
Panel 5: Since she's never heard a recording of her voice before, she panics more and asks if she actually sounds like that.
Panel 6: She's genuinely upset because she cannot stand the way she looks.
Panel 7: Since her need to despise herself is the most powerful need she has, she begs Phil to turn off the video so she doesn't have to look at the monster with the horrible voice any longer.
Panel 8: Since Phil has dealt with her distorted self-image all his life, he is as reassuring as possible when he said that it's over. She asks "It is?"
Panel 9: Rather than point out that Phil has merged with the sofa, she baffles everyone by asking him to show the movie again.
Summary: This is because she is probably having a fat day and needs proof that she is too hideous to be loved and has a voice that sounds like gravel on a washboard so she can shout down the lying people who want to take advantage of her by saying that there's nothing wrong with her.
