Allison Janney appears as Susanna in this episode. Back in Episode 9.8 (The Two Hundredth (2001)), she played the part of Phyllis, a woman who called into Frasier's (Kelsey Grammer) radio show with a description of her missing cat.
The title is a variation of the nursery rhyme "Three Blind Mice."
Bellamy Young, who plays Mellie Grant in the television show "Scandal," plays the owner of a book store and prospective love interest for Frasier. She is one of four "Scandal (2012)" cast members to guest star in "Frasier": Jeff Perry (Cyrus Beene in Scandal) portrays the father of one of the other National Spelling Bee participants in War of the Words (2002); David Bucatinsky in Scandal plays the jewelry clerk in "The Proposal"; and Tony Goldwyn (Fitzgerald Grant in Scandal) portrays a garbage man Roger, a love interest for Roz (Peri Gilpin) in " Love Stinks (2001)."
Lisa (Bellamy Young) and Susanna (Allison Janney) also appeared on an episode of "The West Wing" (1999) together.
