At the beginning of the episode, Kayla's daughters tell her that Sally Ayersman has been teasing them, to which Kayla responds, "If Sally's mean to you again, I'm just gonna have to key her daddy's new convertible." However, later in the episode, House blackmails a surgeon into doing Kayla's liver transplant. The surgeon is a Dr. Ayersman, whose wife, getting an "anonymous" tip about her husband's cheating, decides to key his new convertible. In House's words, "Enough irony for us all."
In an interview, Robert Sean Leonard said that the accent he used to imitate Dr. Chase in this episode came from Batman Begins (2005), specifically when Alfred (from Batman) says, "Never."
Another episode where the team isn't actively working a case. However, the group discusses a previous case in which Chase and House appealed before the Disciplinary Board.
