W.C. Fields was known for his proclivity for alcohol on and off screen and sometimes inbetween
One day the producers appeared on the set to plead with Fields: "Please don't drink while we're shooting—we're way behind schedule"... Fields merely raised an eyebrow. "Gentlemen, this is only lemonade. For a little acid condition afflicting me." He leaned on me. "Would you be kind enough to taste this, sir?" I took a careful sip—pure gin. I have always been a friend of the drinking man; I respect him for his courage to withdraw from the world of the thinking man. I answered the producers a little scornfully, "It's lemonade." My reward? The scene was snipped out of the picture.
