I think there's a lot of, unfortunately, unfunny ventriloquists out there, so they've got a bad rap. It came after Edgar Bergen because everybody had a little cheeky boy dummy like Charlie McCarthy, and everybody decided to become a ventriloquist because Bergen had popularized it. He brought it back from the doldrums of vaudeville.

I've skewered whites, blacks, Hispanics, Christians, Jews, Muslims, gays, straights, rednecks, addicts, the elderly, and my wife. As a standup comic, it is my job to make sure the majority of people laugh, and I believe that comedy is the last true form of free speech.

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.

When I have a creative insight, there is a high. I think back in the day, I made music as much as I did because it made me feel so good. I think you could argue that there is a creative addiction - but, you know, the healthy kind.
