Grandpa's Birthday: Grandpa's about to turn 81 years old, and he figures that since no one in his family has lived past 81, he's going to die soon. Arnold takes him to Dr. Steiglitz "the first doctor Phil's seen in over twenty years" who's amazed that Phil's so healthy for his age, and states that Phil could easily live another 70 years, possibly more. Phil, however, ignores this and still thinks he's going to die. So Arnold and Grandpa spend time together after Gerald tells him to do. Road Trip: Helga is stuck going on a trip to South Dakota with her mother, Miriam, who manages to lose their money and the directions, but could save the day by winning a mechanical bull-riding competition.
