(Strip Number 5040, Original Publication Date, 29 October 1988)
Panel 1: As John does some paper-work, he asks a terrified Lizzie what's wrong. What's wrong is that there's THINGS in her room and she can't sleep because she's scared.
Panel 2: As he makes a mental note to use strong, repeated practical urging techniques on the denizen of another room, John tells Lizzie that having looked under her bed, in her closet and every corner, she can rely on its being perfectly safe.
Panel 3: She thanks Daddy for driving the ghosts away and hugs her.
Panel 4: He thought-bubbles that every so often, it's nice to be someone's hero.
Summary: If he really wanted to be a hero, he'd tell the Looming Shape Of Pea-Brained Malice that he needs to get over the stupid belief that just because Lizzie's birth coincided with his being asked to grow up if he wanted to be treated like one, the first thing did not cause the other so LAY THE FUCK OFF YOUR KID SISTER, YOU MONGREL JERK!!
