Quote from the episode Pilot
George Sr.: Did you ever wonder why we moved from Galveston to Medford?
Sheldon: I tend to worry about the bigger questions.
George Sr.: Okay. Well, here's why. Your Dad had a real good coaching job and I saw some grown-ups breaking rules.
Sheldon: And you told on them?
George Sr.: You know what happened?
Sheldon: Justice descended on the rule breakers?
