<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 doesn't 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 . </Li> <Ul> <Li> Betty Smith (voiced by Swoosie Kurtz)--Jack's ex-wife, Stan's mother, and the paternal grandmother of Steve and Hayley . After Jack abandoned them, Stan took care of her and Betty began to depend unnaturally on her son . This relationship evolved to the point where Stan abducted all of Betty's new boyfriends from fear that they would end up hurting her, dumping them on an uncharted island . Betty later marries Hercules, a widowed Greek butcher, who she met through Francine . Betty tells Stan that neither she nor her son need to depend on one another as they once did, finally ending his obsessive protectiveness of her . Stan accepts that Betty has moved on and tolerates their marriage, though only after he has tried to stop them on board their flight to Greece . Betty is still unaware of her son's earlier actions, and all her previous suitors remain on a deserted island, which the two couples sail near after Betty and Hercules get married in Greece . A short time later, Hercules dies as well, once again leaving Betty as a widow . She moves back into Stan's house, living in the attic with a put - upon Roger, who goes by the alias of Tom Yabbo . She later falls in love with Roger and marries him . They take a trip to Niagara Falls where Betty plans to kill her new spouse, to collect the insurance money on a policy that she has taken out on him . Despite Stan's attempt to save his life, "Tom" falls to his death in the Falls, but Stan then notices Roger in a rain slicker leading a tour group, indicating he is fine . Betty manages to collect the insurance money and moves to Paris, France, where she is seen going into a theater to watch "Fast and the Furious 7" enjoying the gay sex scenes depicted . </Li> </Ul> <Li> Betty Smith (voiced by Swoosie Kurtz)--Jack's ex-wife, Stan's mother, and the paternal grandmother of Steve and Hayley .

He is the son of Jack Smith and a Cherokee woman he met in Santa Fe . Rusty and his family visit Stan's family every Thanksgiving . When their paternal grandfather was dying, he left Rusty and Stan $20,000 and some land he thought was worthless . Stan took the cash (which he loses on a bus) while Rusty takes the land, which turned out to have enormous copper deposits . During their annual reunions Stan treats his relatives in a patronizing way believing that they are poor . On a return visit to Arizona it becomes clear that earnings from copper mining have made Rusty the extremely wealthy owner of a desert estate, living in a huge mansion modeled on that of a Roman emperor . Humiliated and jealous Stan unsuccessfully attempts to steal the property only to be expelled by Rusty's security detail . Previously polished and courteous, the now - furious Rusty vows to kill his half - brother if he returns . After Hayley and Jeff rescue Stan, Francine, Steve, and Roger from the desert, Rusty appears with a gun stating that they are still on his property . When Stan asks how much land he has, Rusty states "sooooo much" in a dated and stereotyped Native American response . Rusty is distracted when the half - bodied helicopter pilot returns, giving the Smiths and Jeff the opportunity to escape . </Li> </Ul>
