Add stock and bring to boil. Add escarole, reduce heat, cover, and simmer for 10 minutes. Add meatballs and simmer another 5 minutes. Meanwhile, combine remaining 2 eggs and remaining cheeses in small bowl and stir with a fork to blend gently. Slow pour egg mixture into hot soup, stirring constantly.
Seth MacFarlane voices four of the show's main characters: Peter Griffin, Brian Griffin, Stewie Griffin and Glenn Quagmire. MacFarlane chose to voice these characters himself, believing it would be easier to portray the voices he had already envisioned than for someone else to attempt it.
Most of the time Brian is the only one who can understand Stewie. When he talks to the adults they hear gibberish or a cranky baby or they dismiss most of what he's saying as you probably would if a toddler told you to go @%#$ yourself. A one year old repeats things but does understand what he's saying.
