I *think* this had to do with a current Mary Worth storyline, with a lonely young writer catching a ride to the grocery store with a lonely young divorced man, and her carrying around a bag of groceries for an inordinate amount of time. One of the egregious faults was a baguette missing from her goodies.
From there, the discussion went something like
Grocery bag –> baguette in bag –> the art of Art Frahm (Google him) –> granny panties –> granny panties around ankles –> Mary Worth –> oh dear God!
Yeah, something like that.
