They were talking about Calvin Coolidge.
Oops. I stand corrected.
Just as an aside, there were so many funny jokes about Coolidge. Alice Roosevelt Long said he was weaned on a pickle, and when Dorothy Parker was told that he had died, she asked, "How can they tell?" At one dinner party a guest told him that she had a bet that she could make him say at least 3 words. He replied, "You lose".
