(Strip Number 4729, Original Publication Date, 12 December 1986)
Panel 1: We find Michael, Elizabeth, Dawn, Gordon, and Brian caroling door to door to raise money for Unicef. As the others look at Lizzie as if she's just beamed down from the planet Ork, Michael tells Lizzie "You're only supposed to sing Christmas carols, Elizabeth. You're not supposed to yell 'Trick or Treat.'"
Summary: If this doesn't get her yapping about Schulz, nothing will. Granted, we had to make Lizzie look simple-minded but whatever makes for a gag is okay by Lynn.
