Golden girls weird scene?

There was an episode in the first season. Here is the dialog:
Rose: When you do it do you........?
Blanche: Why, many times, many MANY times!
Rose: What about you Dorothy?
Dorothy: Well how could I, it always seemed to happen before I entered
the room!

during this whole scene, there was a lot of laughter from the audience

MY QUESTION: WHAT WERE THE GIRLS TALKING ABOUT??!!
