Detective Vince Korsak comments that Psi Beta Tau sorority girls, just like in his day, were "foxy, smart." Rizzoli points out that Korsak never attended college, and he replies "I went to a lot of toga parties." The actor who plays Korsak is Bruce McGill, who played Daniel Simpson Day ("D-Day") in National Lampoon's Animal House (1978), which had one of the most famous toga party movie-scenes of all time.
Many of the episode titles are also the names of or lyrics from songs; "in over your head" is part of the opening line of "Let Me Know" by Gabriella Cilmi.
