This episode's vaudeville Afterpiece is titled "Easter Parade."
The role of the newlywed Emily is played by Elinor Donahue, who is best known for playing the eldest daughter, Betty Anderson, on the 1950s sitcom "Father Knows Best". She had begun that role two years before this Burns & Allen episode aired.
Her role here, as a supposedly sheltered young girl who is actually married, somewhat reflects Elinor Donahue's real life situation, where, despite playing a sheltered high school student on "Father Knows Best", she had actually been married since 1955.
