Megan Mullally and Nick Offerman are, of course, famous television stars to you, what with beloved comic roles in "Will & Grace" and "Childrens Hospital" (her) and "Parks and Recreation" and "Fargo" (him). Beyond that, the pair are a wryly humorous, amorous, lovey-dovey married couple (coming up on 13 years of wedlock in September) and co-workers on several projects such as their staged, comic-and-musical look-see into sex and fidelity, "Nick Offerman & Megan Mullally — Summer of 69: No Apostrophe." We caught up with the happily marrieds en route to rehearsal.

You live together. You work together. That's charming. But at a certain point, when does it get to be too much?
Megan Mullally: It only seems like we work together all the time, but it's not that really. That's why when we do do something as one, it's fun. I think even if we did work together all the time, that would be OK. We get along really well. Not long ago we went on vacation for a whole month and that was cool.
Nick Offerman: If there is a limit as to how much we can stand being around each other, we haven't found it. Our work apart from each other means that we're on-again, off-again. When we're together, we usually know that it's finite — say, touring this for two months, then going out and doing something apart from each other. It’s a constant dance.

I know that you two began your romance between 2000 and 2001. Who made the initial move on the other?
Mullally: He did. He asked me — are you kidding?

Was there a theatrical model for this? Some of it feels like Noel Coward's "Private Lives." It seems as if Stanley Donen's "Two for the Road" is an influence.
Offerman: I can't believe that you just said Noel Coward and Stanley Donen. Both are very generous things to say about our show.

When and how did you decide that your sex and married lives were unique enough to brand as entertainment?
Offerman: We have a good time together, and we thought we could translate that onto a stage. But in reality, I think that people would find us disappointingly normal. We're just two people whose relationship requires all the nurture that any close relationship requires. But, the media has mythologized our time as one, so that when we were looking for an excuse to work together, we built a show around that and it was a natural fit. Plus, we both love dirty humor and we love to sing songs, so we wrote dirty, funny songs.
Mullally: Those extensive articles — and they were funny — chronicling the minute details of our lives together cracked us up. The press really seemed in it to win it where our relationship was concerned, so we decided to exploit that, with the premise being that, yes, ours is the greatest love story ever told.
Offerman: And, that yes, with a little practice, you can have this fairy-tale life, just like ours.
