Family Guy Skewers Marie Kondo (and 5S and Lean too?)

I haven't read it, but Marie Kondo's book The Life-Changing Magic of Tidying Up: The Japanese Art of Decluttering and Organizing has been a pop-culture phenomenon the past few years. I've seen some compare her process to the Lean practice of “5S.” Kondo says you should only keep an item if it “sparks joy.”
