The Fab Five (guys from the show "Queer Eye for the Straight Guy") are everywhere. My wife and I joke that when the dolls hit the shelves, their fifteen minutes of fame are over.
What does the author mean in this part? He just said that these guys are popular and then "these dolls hit the shelves" and it's over?
Does he call the Fab Five "the dolls" or it's just some expression I don't know?
