(Dr. Hibbert gives Bart money after retrieving his golf ball.)
Bart: A dollar? What for?
Dr. Hibbert: It's the least I could do. These balls cost five dollars new.
Bart: So I can get a dollar for every ball I find? Then if a cell phone costs $100, how many balls do I need?
Dr. Hibbert: (speaking aside to Dr. Riviera, his caddy) This is why my kids go to private school. (Laughs)
