One of the patients in the surgery is named Darryl Hannah. An obvious play on the actress.
Not only is one of Martin's surgery patients waggishly named Daryl Hannah, it serves as a winking reference to guest star Danny Huston: Both Hannah and Huston co-starred in writer-director John Sayles's political satire Silver City (2004), with Hannah's character seducing, then abandoning, Huston's character.
