When Joey is trying to talk about The Shining in front of Rachel, he says "Remember when Danny sees those two blanks in the hallway" (referring to the twins) and "All blank and no blank make blank a blank blank" (referring to the famous line "All work and no play make Jack a dull boy". Those things do not happen in the book by Stephen King, and are exclusive to the 1980 movie adaptation.
Joey mentions that the main character Josephine "Jo" March from the book "Little Women" has a crush on her best friend Theodore "Laurie" Lawrence. Quite famously, Jo does not have a crush on Laurie; Laurie has a crush on Jo. When he declares himself she does not return his feelings, and the broken-hearted Laurie runs away to Europe and eventually develops feelings for Jo's sister Amy.
