The script of this show contains the following lines: "It's like he's been brainwashed by some cult" (Alan Harper [Jon Cryer] referring to Jake's obsession with his new, much older girlfriend); and, "It could be worse - he could be one of those show-biz kids who goes off the rails" (Berta [Conchata Ferrell], after Jake announces he and his new girlfriend are going to Vegas to get married). By the time this show aired (February 2013), Angus T. Jones, the actor who plays Jake, already had appeared in interviews and Internet videos announcing his contempt for the show and his intention to affiliate himself with a little-known religious group called ForeRunner Chronicles (source: Wikipedia).
Tammy makes a reference to a tattoo of Brad Paisley. Paisley would guest star in a few episodes in season 11
