When Smokey Floyd goes to mark the item off his list, you get a close-up look at it. The item over the one he marks off is "Stole P's HD Cart", referencing the episode of My Name is Earl where he returned Pop's Hot Dog Cart. Upon closer inspection the list is is marking items off on is the same list Earl carried with him in My Name Is Earl (2005).
The main cast from My Name Is Earl (2005) appears and slyly follows along that TV show's premise. Even Jason Lee's character crosses off an item on a paper after fulfilling the good deed.
This episode mirrors both My Name Is Earl (2005) and Almost Famous (2000). The My Name is Earl references occur throughout the episode, and the final plane scene almost perfectly mirrors the plane scene in Almost Famous - with Jason Lee even saying his same line in both.
Burt and Virginia hire a bounce house for Hope's 3rd birthday party, instead of getting a bounce house a girl, Valentina, (Nadine Velasquez), arrives with a small trampoline. When the group performs a song she bounces on it, mimicking her dance moves as Catalina in My Name Is Earl (2005). Her confession on the airplane is that she used to be a stripper, again, mimicking the Catalina character from My Name is Earl.
During the plane trouble scene at the end of the episode, each character makes an admission thinking that are about to die. Andrew, (Ethan Suplee) admits to running over a turtle on the roads, Tyler, (Eddie Steeples) then admits his pet, "Mr. Turtle" was run over a few months before. (referencing Darnell's pet in My Name is Earl). Tyler then confesses to being in the witness protection program, again, like Darnell. A third confession from Tyler is that he slept with Donna, (Jaime Pressley), referencing Darnell Turner's affair with Joy Hickey.
