When talking about death, Turk and JD say their first day in heaven will be by the milkshake pool on the lesbian cloud. This is not a new plan. They mentioned this exact same plan in the season 5 episode My Way Home (2006).
Christa Miller (Jordan) and Courtney Cox (Dr. Maddox) talk about going out for drinks because "cougars" drink for free. Both actresses would go on to star in Cougar Town (2009).
Dr. Cox, Elliott, Janitor, or Kelso did not appear in this episode.
When Turk mentions playing football, he says he played football as a safety. Donald Faison who plays Turk also starred in Remember the Titans (2000). In the movie, he plays Petey Jones, a running back that is switched to safety.
