Sssssssssssssssssss. That’s the sound of steam coming from the set of “Cougar Town” while filming was under way on episodes with Courteney Cox Arquette getting it on with her first “cub,” Nick Zano.

The actor of “What I Like About You” and “Beverly Hills Chihuahua” fame describes his average day: “You read what they put in there for you. Usually, it involves being wet, a bathtub scene or a bed scene. So, I’d go into my trailer, open up my closet, see five pairs of boxers and a terrycloth robe. So it would be, put on the boxers, put on my robe, walk over to the set, talk to the camera guys — ‘How was your weekend?’ The AD pulls back the sheet. Courteney comes in. Talk about her family. ‘How’s David doing? How’s Coco?’ She gets into the bed, I get on top of her and we start making out.”

And there you have it. But wait. Zano adds the mandatory advisory, “As much fun as it sounds, it’s also pressuring. We can see maybe 14 people standing around, a group of big Teamsters text messaging while we’re fake making out. And it’s very, very choreographed. You have to remember how far up your shoulder goes, how high you can bring your head up.”

Zano’s story line runs over six episodes, the funniest being next Wednesday’s (10/28), according to him, and in a couple more weeks, “There’s my last one. It’s a big one. It’s a doozy,” he says.

As for what he thinks of the whole “cougar” trend? “As a former young man, I applaud it,” he says. “I think guys could use a mature woman. It’s truth. The woman teaching a younger man thing — that woman basically takes that young man to school. He carries that with him when he dates younger women.”
