<P> David Jacob `` D.J. '' Conner is played by Michael Fishman ( Sal Barone in the pilot episode ) . Born in 1981 , David , better known by his initials D.J. , was the youngest of Roseanne and Dan 's children and their only son until the birth of Jerry Conner , in 1995 . D.J. is more simple - minded , naive , and boisterous than his older sisters , who frequently taunt him . In the first episode of season three , it is stated that while Becky and Darlene were planned pregnancies , D.J. was a `` surprise '' . As he grows up , D.J. 's storylines deal with more mature topics such as masturbation and human sexuality . Later episodes depict D.J. as having a close , brother - like friendship with Becky 's husband Mark . He is also shown to develop an interest in filmmaking : he repeatedly asks Darlene if he can videotape her giving birth . He was one of the only characters that was n't changed in the final episode of Season 9 , which has since been ret - conned out of existence . </P>
