Nah, the money is in creating an animated show centered around a family where the father is a dolt, the mother is reasonable, the eldest son is a troublemaker, the middle child is an unappreciated nerd, and the baby shoots the father's boss. You can create an entire city of characters around the family too.
If you're really ambitious, you can change it around to make the baby an evil genius, and toss in a left-leaning pretentious talking dog.
