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.

The best place to find material is in real life. I've always maintained that it's not until the mid-20s that you have enough of a life to draw from. There's nothing better for a comic than to go through some bad stuff - and some good stuff, like getting married.

I'm guilty of being fascinated by gadgets and toys and technology, but any penny that I spend, I try to make it be a part of what I do for a living. Because then you are forwarding. You are forwarding that art, forwarding that career ahead.

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.
