Three endings to this episode were filmed. The first ending ended with "Clark....," and it was shown at the tail end of "And The Answer Is." Strangely, "...We Have A Lot To Talk About", the third season premiere, opened with Lois saying "Who's asking, Clark or Superman?" There was also a third ending, with Lois saying "Yes," that was never used. All of these endings were filmed for this episode, and the decision to use the "Clark..." was made at the last minute.
When investigating the scent lingering in his apartment, Clark asks a flower salesman, "Didn't you play for the Bills?" The salesman responds he did until he blew out his knee. This exchange is a reference to Dean Cain's personal life. After graduating from Princeton, Cain signed as a free agent with the Buffalo Bills. During his rookie season training camp, he suffered a career-ending knee injury.
