When they are forced to return to the warehouse by the airport closure, the kidnapper says, "By the time the police figure any of this out, I'll be on the beach earning 20%." This is a nod to the movie "Die Hard" where Hans Gruber says the exact same line.
During a scene in the warehouse where Delinda is being held, two of the kidnappers are referred to as "Mark" and "Robb". This is presumably a self-referential moment inserted by Mark Cullen and Robb Cullen, who wrote the episode.
At a point toward the end of Delinda's captivity, the kidnapper tells her that she's "very photogenic" and sarcastically asks "have you ever been a model?" Molly Sims (Delinda) was a top-rated model before joining the show.
