To kill Lois and the Fat Man AND take over the world
Seems like the answer is No, they don't understand him like they do the dog.
There are no named songs Chitty Chitty Death Bang.It's all music composed by Walter Murphy.
There is an episode, "Family Goy" where Peter tears apart Stewies crib and uses the pieces to make a giant cross for Lois.
He doesn't have one. He does however have a younger half-brother named Bertram, at least "younger" in the respects he was born after Stewie but in his 2 appearances after he was born he appeared the same size and age.
Because the original Peanut Butter Jelly song featured an animated dancing Banana image.
Humble personality is basically simple personality or boring personality.
