For this episode, the freeze frame is from this earlier episode. This is the only time in the show's entire run that the freeze frame does not belong to the current episode. The main reason for this unusual choice is that the chosen image pays tribute to Kellie Martin's Lucy Knight, as the earlier image shows her smiling and looking hopeful about her future, in contrast to the tragic conclusion of her story here.
The song playing as Chuny comes into Doc Magoo's, to tell the others that Lucy has died, is called Samba Pa' Ti by Santana. The same song was first played at the end of Lucy's debut.
