This is the first episode in which Rose mentions her hometown of St. Olaf, which would later become a running gag.
Jerry Hardin (Professor Cooper) and James Staley (Dean Tucker) both appeared in later episodes that had ties to Blanche. Hardin played Blanche's boyfriend Gary in "Little Sister" (S.4 EP. 21). Staley played Dr. Manning at the sperm clinic in "The Accurate Conception" (S.5, E 2). He informed Blanche and Rebecca about the artificial insemination.
