Paperweight's Legacy Roadtrip
After the events in The Nuke From Moreland, Paperweight was diagnosed with chronic lukemia.
Having already been super pissed off by all his other old people problems like his medicine box the "leash of curses," he decided that instead of seeking treatment he would kickstart earlier his plan of retiring to and dying in Fanton.
He sent in his resignation form, got his endless source of free labor -- Goose, and asked her to drive him to the border, where he had people waiting to drive him to the old people home.
