What Was Winston Churchill's Most Famous Quote?

Well, my personal favorite is his response to a female critic who said to him, "If I was your wife, I would poison your coffee!" He replied, "Madam, if I was your husband, I would drink it."

I think his most famous quotation was his "we will fight on the beaches" speech (which was allegedly delivered by a body double, actually).

I really like " the outside of a horse is good for the inside of a man" and " no hour of life is wasted that is spent in the saddle"
