Bill Stoshack

Bill Stoshack is Joe's father, who has been paralyzed from the neck down since Book #5 when he got into a car crash, but it said in later books, like "Roberto and Me." that he was paralyzed from the waist down since he can wheel himself in a wheelchair. He usually tries to use his son's time-traveling powers to make money, as before he was paralyzed he was always getting laid off. He has a huge baseball card collection.
