Oscar Wilde
Hey, thanks. It does sound more like something Oscar Wilde would have said.
After a bit of investigating, it’s fascinating, the quote has been attributed to: George Bernard Shaw, Winston Churchill, Groucho Marx, Mark Twain, W.C. Fields, Bertrand Russell, H.G. Wells, Woodrow Wilson and others.
