This episode aired in January of 2001 when AMC's programming focused on uncut classic films, which explains the reference to Fiddler on the Roof (1971) when the channel changes away from the Superbowl to AMC; it wasn't until 2002 that AMC changed their formatting to include movies of all eras along with original programming, including cut movies and commercials; AMC has continued to rebrand and change their formatting over the years and has become known for their original television series The Walking Dead (2010), Breaking Bad (2008), and Mad Men (2007), to name a few.
