Determined to prove to her that he is a responsible adult, Peter goes on business trips to Chicago, New York City, San Francisco and St. Louis, returning as an intelligent, classy man.
When Lois goes out with Bonnie to the shooting range (which creeped Joe out on her last visit since the target was a paraplegic man), she tells Peter to take Stewie to the park in order to spend time with him.
He makes many more business trips to San Francisco, St. Louis, and New York, picking up more learning until he finally returns home refined and cultured, surprising his family.
However, the new Peter's culture begins to alienate his friends and obstruct the usual family entertainment, replacing the TV with a bookcase with different books where one of them happens to be Game of Thrones.
Our reset button this week takes the form of Lois and Brian sending Peter to the dumbest city in the world to become lazy and irritating again: Tucson, Arizona.
