I liked it better when W.C. Fields was attributed to have said it (although it isn’t definite that he did).

He did say some fun things in about booze in films though:

I was in love with a beautiful blonde once, dear. She drove me to drink. That’s the one thing I’m indebted to her for.

I exercise extreme self-control. I never drink anything stronger than gin before breakfast.

Whilst traveling through Afghanistan, we lost our corkscrew. Had to live on food and water for several days.

He also once said something serious which is also my own policy:

Hell, I never vote for anybody. I always vote against.
