<P> In the episode "Portrait of Francine's Genitals", Jeff revealed he took Hayley's last name, making him Jeff Smith . Later in the season, in the episode "Roger's Baby", Jeff is reborn as a human, via Roger eating his brain and rebirthing him . </P> <Ul> <Li> Jack Smith (voiced by Daran Norris)--The abusive father of Stan, Rusty, and Nicholas Smith and the paternal grandfather of Steve and Hayley . For most of his life, Stan believed his father to be a secret agent but, in reality, he was a jewel thief . After the man Stan paid to pretend to be his father died, "Grandpa Smith" (the real Jack) dropped in on the family . Roger developed a "boy crush" on Jack but the other family members were wary of him . Roger goes so far as to dress like him and keeps Francine locked in a cage because Jack put her in there . Jack has gray hair, sports an eyepatch on his left eye (based on the traditional look of Marvel Comics' super-spy Nick Fury), but otherwise resembles his son Stan . Roger compares him to Kurt Russell's character Snake Plissken from Escape from New York and Escape from L.A.. Jack's second appearance is a single line of him being heard but not seen in a flashback to Stan's childhood where he asks his father to read to him . Jack replies with a single line "Who the hell are you?" Jack makes his third appearance in a flashback showing him running out on Stan and his mother . Jack makes his fourth appearance in which Steve decides to visit him in his jail . When it is discovered that Stan never learned to ride a bicycle because his father was not there for him at the moments of need, Steve decides to reconcile them both by making Stan visit the jail where Jack is passing his sentence . After the latter one is released on Stan's parole, Klaus suggests the three of them should go camping as an act of reuniting Stan with his own father . It turns out to be a bad idea as Stan soon finds out that Jack is using his grandson to appeal to Stan so that he could defend his own father in court during the next trial verdict . Jack then turns Steve to his side and both run away, all while Steve begins viewing Jack as a father figure . When things get out of hand, however, Jack confesses that he is a crook who was up to no good all this time and wishes Stan would not lose Steve in times of need as much he himself once did . When Stan finds out about this, he forces himself to ride his bike to the courthouse to give his own word of reference about his father's verdict, but arrives too late, much to both Jack's and Steve's contempt . Jack is sentenced to five more years of prison, but is not bothered by the idea now that he has formed a genuine relationship with his grandson, and Stan promises to visit him this time . In "Blood Crieth Unto Heaven" (which was depicted in the style of a stage play), it turned out that Jack had left the family after Stan found his mother making out with Jack (who was disguised as a clown at the time) and that he was eventually arrested after the police commissioner that Stan idolized and invited to his birthday called for police backup while investigating the thefts of the fruits from a fruit truck . In "Minstrel Krampus" (which was depicted in the style of a Christmas story), Jack is revealed to have trapped Krampus while as a child . When Stan frees Krampus to teach Steve a lesson and it does not go well, Stan had to use his CIA connections to get Jack out of prison . After being shot by Santa Claus while protecting Stan Smith, the blood of Jack and Krampus combine which revives Jack as Krampus . In this form, Jack plans to continue his predecessor's job in tormenting naughty children . In the episode "Ninety North, Zero West," Jack Smith is still in his Krampus form as Stan persuades him to help save Steve from Santa Claus at the time when he plans to awaken the Sumerian giant Humbaba . In the episode "Klaustastrophe.tv", Jack reappears, now a human again . </Li> </Ul> <Li> Jack Smith (voiced by Daran Norris)--The abusive father of Stan, Rusty, and Nicholas Smith and the paternal grandfather of Steve and Hayley .
