When Vito is trying to make it through another day of construction work, his thoughts are heard in first-person voiceover rather than in spoken dialogue, one of the few times, if not the only time, when such a technique was ever employed in the series.
Tony and Silvio are shown carrying packages containing bootleg DVD box sets of the 1949 film Sands Of "Iowa" Jima (Sands Of Iwo Jima).
Karen Lynn Gorney makes a very brief appearance here as "Judy" with one line of dialogue when she catches Vito asleep at work. Gorney had infamously reached her show-biz career peak some 29 years prior to this role when she played the romantic co-star of John Travolta in the iconic Saturday Night Fever (1977).
This is the only episode directed by Steve Shill, one of the few British-born directors (and now a prominent one on American TV) to ever helm a The Sopranos (1999) episode.
At the library, Vito pulls from his jacket a bottle of vodka whose label resembles that of the well-known brand Smirnoff, but the name on the label is "Sknokoff" (i.e., a knockoff of Smirnoff).
