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.

One tradition I have with my friends is that when one of us gets married, we have a ton of fragrance oils and pretty bottles at the bachelorette party. Everyone puts a drop or two in a bottle for the bride and makes a wish, and the bride wears our creation on her wedding day.
