Hey, TV-nostalgia buffs! Aching for another Growing Pains reunion movie? Well then, you'll be pleased to know Growing Pains II: Home Equity just wrapped production in New Orleans, which doubles for the Seaver family's Long Island home base. All of Pains's original cast is on hand — TV mom Joanna Kerns even directs — but, unsurprisingly, Leo DiCaprio isn't coming back as Luke.

"I'm sure they thought of it," Alan Thicke (aka Dr. Jason Seaver) tells TV Guide Online, chuckling. "And I'm sure [Leo's] not available." Fortunately, the real-life pregnancy of Tracey Gold — whose career was recently "executed" on Celebrity Mole: Yucatan — will help make up for the personnel shortage. Gold's pregnant, so Carol's expecting onscreen, too.

"I'm still trying to get used to the concept of playing a grandfather," the 57-year-old Thicke says. "I've now moved into what I call the 'ferzage' category. It's a new demographic that I invented. That's where people start saying, 'Well, he looks good for his age'."

Will we see Carol's baby birthed in the TV movie? "Worse than that," Thicke mock laments. "[My grandchildren] are semi-grown children [around] 11 or 12. These are the children of Kirk Cameron and Tracey's characters. They were little tykes in the first [reunion] movie. So I'm now a grandfather to kids the same age as the children were back in the series!"

This fresh dose of Growing Pains nostalgia — which will likely air this fall — sure doesn't hurt Thicke's career as an author of fatherhood-advice books. The next one, How to Raise Kids Who Won't Hate You, is due out in the fall. And as host of the TV series Animal Miracles, Thicke tries to set a good parental example for fellow Animal Planet personality Steve Irwin. "I won't be dangling my 1-year-old in front of a crocodile, that's all I can tell you. No dangling!" — Additional reporting by Ileane Rudolph
