In S1E16, Lorelai is at Friday night dinner sans Rory, and she’s feeling awkward. She turns to some figurines on an end table for a discussion topic and says, “Oh god, Mom has gone a little crazy with the figurines here, huh? A little ‘Kathy Bates?’ Although, you probably haven’t seen ‘Misery,’ which is a good thing, cuz Rory couldn’t sleep alone for a week after we watched it.”
“Misery” is a 1990 film based on a Stephen King novel. It stars Kathy Bates as Annie, an obsessive and murderous fan who captures a famous author and forces him to write a story for her.
