Original Commentary
It's always a bad sign when they go right into selling off their belongings. This of course is a reference to the comic that aired on March 3rd 2004 that showed that in fact everything that Brisbane owned can fit in one box (fortunately Kimberly has since taken him out shopping for slacks).

Modern Commentary
Anxiety plans.
Impractical, but it keeps her moving.
Kimberly can get $3 for a used box, though.- Terrence
