The episode "[[Brother from Another Series]]" introduces Bob's brother Cecil. After writer [[Ken Keeler]] was assigned to write an episode featuring Sideshow Bob, he drew inspiration from episodes of ''[[Frasier]]''. He decided to incorporate elements of Grammer's other show into the character of Sideshow Bob, and designed Cecil to resemble Grammer's brother on ''Frasier''.<ref name="Keeler"/> Cecil is voiced by [[David Hyde Pierce]], who portrayed [[Frasier Crane]]'s brother [[Niles Crane|Niles]]. Pierce commented, "Normally, I would not do something like this. But how often do you get a chance to work with an actor like Kelsey Grammer and, more importantly, play his brother?"<ref>{{Cite news |title=TV Tidbits |work=[[The Hamilton Spectator]] |date=February 20, 1997}}</ref> Several of ''Frasier''{{'s}} producers were asked to review the original script and provide feedback. Their comments were positive; they only expressed concern with a very brief scene in which Cecil talks to a visible character whom he refers to as "Maris". In ''Frasier'', [[Maris Crane]] is an [[unseen character]], and the producers of ''Frasier'' asked that the scene be removed.<ref name="Keeler"/> Many of the interactions between Bob and Cecil were based on those of Niles and Frasier.<ref name="Keeler"/> Cecil was drawn to resemble [[David Hyde Pierce]], while retaining a visual similarity to Sideshow Bob. According to director [[Pete Michels]], it was difficult to draw Bob and Cecil standing together, because of their comically oversized feet.<ref name="Michels">Michels, Pete. (2006).

Cecil returns in [[The Simpsons (season 19)|season 19]]'s "[[Funeral for a Fiend]]", which introduces the brothers' previously unseen father, Dr. Robert Terwilliger, played by [[John Mahoney]].<ref name="Futon">{{cite magazine |title=The Simpsons |magazine=[[Entertainment Weekly]] |date=September 4, 2007 |url=http://www.ew.com/ew/article/0,,20054579,00.html |access-date=January 1, 2009 |archive-date=February 4, 2009 |archive-url=https://web.archive.org/web/20090204020429/http://www.ew.com/ew/article/0,,20054579,00.html |url-status=dead }}</ref> Mahoney portrayed [[Martin Crane]], the father of Grammer's and Pierce's characters in ''Frasier''.<ref name=Frasierreunion>{{cite web |url=http://www.digitalspy.co.uk/tv/a75660/frasier-cast-to-reunite-for-simpsons.html |title=''Frasier'' cast to reunite for ''Simpsons'' |date=September 14, 2007 |author=Dadds, Kimberley |access-date=October 15, 2007 |work=Digital Spy}}</ref> Whereas in ''Frasier'', Mahoney played the "down-to-Earth, average guy" to Grammer's and Hyde Pierce's "uppity snobs", Robert Terwilliger Sr. was portrayed as equally highbrow as Bob.<ref>{{cite web |author=Canning, Robert |title=The Simpsons: "Funeral for a Fiend" Review |website=IGN |date=November 26, 2007 |url=http://tv.ign.com/articles/837/837504p1.html |access-date=January 3, 2009}}</ref> His wife, Bob's mother, is Dame Judith Onderdonk, "the finest classical actress of her generation." She sports the same curly spiked hair as her two sons. Bob also has a wife named Francesca (voiced by [[Maria Grazia Cucinotta]]) and a son named Gino, both of whom were introduced in [[The Simpsons (season 17)|season 17]] episode "[[The Italian Bob]]" and returned for "[[Funeral for a Fiend]]".<ref name="TIB"/>
