Wilford Brimley made a guest appearance as the Post-Master General of the United States. The actor's father was a postmaster.
Wilford Brimley, as the Postmaster General, sits on a desk and threatens Kramer (Michael Richards). The scenario parodies Brimley's performance in Absence of Malice (1981) where, as an Assistant U.S. Attorney General, Brimley threatens a room full of lawyers and subordinates using similar statements.
Newman's (Wayne Knight) pulling up beside Kramer (Michael Richards) and telling him: "This is the way it will happen. Someone you trust will ask you to get in the car" is a parody of the penultimate scene in "Three Days of the Condor" (1975).
This episode marks the first time anyone mentions the word "email."
The Wiz commercial is loosely based on a commercial for an electronic store in the Northeast called "The Wiz" where people would dance around saying "Nobody beats The Wiz." The Wiz retail stores have been defunct since 2003.
