Churchill was known for some famous ones, some of them probably apocryphal.
In one instance he was speaking in public after a few drinks too many, and offended a woman listener, who publicly upbraided him with, “You’re drunk, Mr. Churchill!” He was supposed to have responded completely calmly and deadpan, “Quite so, madam, but in the morning I will shall be sober. You, however, will still be ugly.”
Another time he was introducing a speaker to an audience, and he gently but firmly put him down by introducing him as “a modest man, with much to be modest about”.
Dorothy Parker got off a good one (many good ones, I’m sure!), but one time when she and a younger woman reached an open door at the same time, the younger woman deferred to her, saying, “Age before beauty.” Ms. Parker snidely responded, as she swept through the doorway, “Pearls before swine.”
