Louis Armstrong was the greatest jazz musician of the 20th Century. One of his most endearing qualities was that he never took himself too seriously. This was reflected in his music and in his approach to other aspects of the entertainment business.

He was such a big believer in a herbal laxative called Swiss Kriss he even recommended it to members of the British Royal Family. And advertised it as below.
