There was a scene in Postcards from the Edge where Meryl Streep walked in on her mother, played by Shirley MacLaine, mixing up a morning health smoothie, topped off by a generous helping of vodka.
When confronted, MacLaine said something like, "I used to be an alcoholic, now I just drink like an Irish person."
My Scots-Irish mother and I got a big laugh out of that one. :-)
