Nick Offerman and Megan Mullally “live in Hollywood and we've stayed together for more than 18 months. That qualifies us as apparently being an amazing showbiz couple.”

Though Offerman insists that the actors, best known for their respective roles on “Parks and Recreation” and “Will & Grace,” maintain relatively boring lives, their marriage generates adoration and claims of “comedy power couple” from fans and media outlets. It's also the subject of their comedy show, “Summer of 69: No Apostrophe.”

After writing and touring the act for the first time last year, Offerman and Mullally revamped the show this time around, adding several songs and “punching up” a few moments. Offerman called from Richmond, Va., to speak about the show, the couple's relationship and more before bringing “Summer of 69: No Apostrophe” to the Hippodrome Theatre on tonight. (Mullally wasn't available.)

Am I just speaking with you today, or also Megan?

I'm afraid it's just me. Megan and I just made love and she's laying here quite flushed and ravaged. She probably won't be conscious again for another 90 minutes or so.

?

How would you describe “Summer of 69: No Apostrophe”?

Filthy. It's an incredibly fun and raucous musical representation of our marriage. It's very song-heavy, and we're like an old showbiz couple. I play the guitar and Megan plays the ukulele and we do an assortment of songs about many of the different things that we do to each other when we're naked, and it's a lot of fun.

?

How did you and Megan meet?

We met doing a play in Los Angeles in 2000 at a company called the Evidence Room in a play called “The Berlin Circle.” She had just done the first two seasons of “Will & Grace” and I was living in an unfinished basement in Silver Lake, so we were quite an unlikely pairing. But apparently love does not depend on logic in all cases, thankfully.

?

Does working together come naturally to you? Have any challenges come with working with a spouse?

Not really, I mean we really love working together. I'm surprised when so many people say to me, “Are you crazy? I would do anything to get away from my spouse, and you guys choose to go on a road trip touring together?” It makes me think that all of those people maybe married the wrong person, because we just simply really get along. We're in a relationship like anybody, so we have the occasional dust-up, but it comes with any marriage, and I think that working together and being collaborators probably just improves our powers of compromise.

?

Some couples have a “celebrity exception,” a famous person they're allowed to cheat on their spouse with if they ever encounter the celebrity in person. Does this rule apply when you're married to a celebrity?

I can only speak for our household: I think that's dumb. I suppose maybe because I'm married to a goddess, it would not occur to me to come up with someone with whom I would rather go to bed. But that's the boring side coming out. I don't think that's a very nice thing to say if you are married to somebody, that I get a free pass to bang Dwayne “The Rock” Johnson. Sure, he's cute and he smells like delicious papayas. But I took a vow.

?

Through the show, what have you and Megan learned about each other, or about acting and comedy from each other?

It's an ongoing education, because we're both very experienced theatrical performers, meaning we trained for the stage and then we transitioned into TV and film, and we continue to work in all three mediums. When you then begin performing sort of in the comedy genre, where you're kind of presenting yourself, your own persona on stage, it's a whole new ball game and something that we're learning more and more about every night. … Megan is an incredibly refined singer. She's done Broadway shows and she has a batch of records out and I'm very mediocre, and so she's teaching me how to be a better singer, plain and simple. According to my coach, it's a muscle; like anything else, you've got to exercise it. I've gone from I think a C- to, I might be sneaking up on a C+ in my own presentation. And maybe, maybe Megan is learning a little bit about the value of coarseness in presenting a showbiz performance. That's a serious maybe.

?

For those who don't have the privilege of being able to come to the show, is there any tidbit or secret you'd like to bestow?

No. You gotta come to the show. If you don't come, that's what's so fun about live performance — if you're not there you don't get magic. I'm not sure where John Waters is hanging his hat these days, but whenever I hear “Baltimore” I immediately think of either the Ripken family and/or John Waters. Sometimes I imagine them all together. I don't know John, but I think he would really love our show. If you could drop off a memo at his place I'd appreciate it.

?

He's still here. Maybe you and Cal can be in the next John Waters feature.

That would not hurt my feelings. Maybe we'll get Dwayne “The Rock” Johnson.
