At approximately 18 minutes into the episode, as James Hurley walks toward the door as Big Ed brings Nadine home from the hospital, a small glass figurine of a woman's head and upper chest can be observed with an eye-patch over "her" right eye (not unlike the one Nadine wears over her own left eye).
Van Dyke Parks, who plays Leo's lawyer, Mr. Racine, is actually a film composer of some note. He's worked with director Robert Altman on Popeye and The Company, as well as scoring several popluar children's movies such as The Brave Little Toaster and Sesame Street: Follow That Bird.
When Twin Peaks was rerun on the Bravo cable network in 1993, David Lynch wrote new introductions for each episode that were performed by Catherine Coulson as The Log Lady. The one for this episode was thus:
"Sometimes nature plays tricks on us and we imagine we are something other than what we truly are. Is this a key to life in general? Or the case of the two-headed schizophrenic? Both heads thought the other was following itself. Finally, when one head wasn't looking, the other shot the other right between the eyes, and, of course, killed himself."
