My mom's brother was gay, and he actually passed away from AIDS when I was 13. He was quite a character, but he also worked at the electrical plant, so he was this complicated guy with a big laugh who would wear a trucker hat and do impressions. He was gay, but to me, Uncle Alan was just the funniest person in the world.

Frankly, as much as I love to improvise, it hasn't been difficult to stick to the script on 'Mad Men.' The writing is so precise, and the story so carefully crafted, that I don't think there's room - or need - for ad libbing. I could never come up with dialogue as lovely as these writers do, anyway.
