The slate ("clapstick") used to begin a 'take' in Ricky's screen test is marked as follows: EMPIRE Prod / 9-17 / Director: Aldworth / Cameraman: Wester / Ricardo Test / Take (1, then 2, then 3, and so forth). "Aldworth" refers to Jack Aldworth, assistant director on this episode.
The chain lock that Fred installed on the Ricardos' front door in the previous episode is no longer there.
One of the starlets listed in Variety is Yvonne De Carlo, who later played Lily Munster in The Munsters (1964). When Ricky realizes that Lucy is jealous, he refers to her as the - albeit unintentionally through his accent - the "green eyed munster."
Lucy is reading the November 1954 issue of "Modern Screen" featuring Debbie Reynolds on the front cover.
