well yea, their all similar scenarios if you look at it.
family guy...
husband wife 3 kids a dog
5 things.
simpsons
husband wife 2 kids cat dog
5 things again..
now american dad is a bit different.
husband wife 2 kids fish alien
6 characters but essetially the same scenario.
in all of the above the dads are stupid... one kid is a nerd/loser one kid is pretty mischief making, one character is evil, (in the simpsons i think the cat is evil) and they all have at least one pet.
now IN YOUR opinion, which one rules all the others?
