space's only occupant except in two episodes, when he was replaced by Ken and Erin, respectively, and would appear always wearing similar clothes, with a wooden chair, a lightbulb, and the bland walls. Frequently, props appeared for one-shot gags in the neutral space. Very rarely would anything from the Live Story appear there (one notable exception was Dave's suicide note in "Private Dave"), nor would anything from the neutral space appear in the Live Story. There are many allusions to the neutral space being Titus's mind, though it is never said outright. On a few occasions, the neutral space is used to demonstrate the passing of time, or Christopher will do something "in" the neutral space when he is really just thinking about it while doing it; we only see his thought process. Also, as in "The Trial", sometimes he will say something in the neutral space and not realize he is also saying it in reality, like when he calls the prosecutor an idiot, thinking he only thought it. Following the credits in the final episode of the series ("The Protector", not "Insanity Genetic" or "Homecoming"), Titus drags the bare wooden chair into the middle of a real life street, sets it on fire, and walks away, whistling part of the theme song. Flashbacks Flashbacks—always introduced from the Neutral Space–were frequently used for character development and background. Flashbacks generally went back to one of three time periods: when Titus was five, ten, or seventeen. Three different child actors played the five- and ten-year-old versions of Titus, the latter sometimes joined by five-year-old and ten-year-old versions of Dave and Tommy. Flashbacks to high school with the seventeen year old Titus had all of the current actors playing the younger versions of themselves. To compensate for being too old to believably play the roles, the actors have humorously exaggerated costumes and mannerisms. Except for a few flashbacks in "Grandma Titus" that featured Ken as a child, Stacy Keach is the only one to appear in all of his character's flashbacks; only his hair and clothes change with the times. The flashbacks themselves had no specific format other than being quick, one laugh gags. They frequently showcased Ken Titus's unique approach to parenting, relationships, and drinking. The women that Ken is shown dating (or even married to) in these flashbacks are frequently not given a name, and their faces are rarely shown.
