The technophobe in the "Last Donut" sketch states that the closest thing to "modern technology" is a "Mini Victrola" and pulls up a small phonograph, going on to herald the benefits of vinyl over CDs. The phonograph he holds up clearly has the name "Edison" on the front.
Alyssa Milano can be seen briefly in the audience during the "4 Voices" sketch.
Mary Lynn Rajskub makes her last appearance on the show. According to an interview on a DVD set for The Larry Sanders Show, she and creator/star David Cross had been dating, and when they broke up, her association with the show ended, too.
The DVD version of this episode features commentary from David Cross, Jay Johnston, Tom Kenny, Bill Odenkirk, Bob Odenkirk, Brian Posehn, and Paul F. Tompkins.
