in real life. ABC's Chris Connelly caught up with the cast reuniting for the first time in 16 years. ? When a man loves a woman ? Reporter: In 1988 "The wonder years'" first episode had this kiss between Kevin Arnold and Winnie cooper, played by Fred savage, 11, and 13-year-old Danica Mckellar. The one good thing about getting a first kiss on camera is you know for sure it's going to happen. We were both really scared and nervous and didn't know what was going to happen or if we were going to do it right. Do you breathe in through your nose? Do you hold your breath? Reporter: Now the cast of this set in the '60s dramedy, savage and Mckellar, along with Olivia dado and Jason Hervey, Kevin's sister and bullying bro, Adam mills and Dan lawyeria as the patients and josh steviano who played Kevin's best pal, have reunited for the first time in 16 years. "The wonder years'" cast members seemed to avoid the child star pitfall. That was our parents. Our parents kept us really grounded. We all had a really strong work ethic, too. Don't be a child of entitlement. Reporter: Dabo thrived as an action, here as a producer. Sal Gano is now a lawyer. Some think Paul was played by a shock rocker. Josh, how many times a week do you get asked if you're Marilyn Manson? Thank you. Thank you, somebody. He just got asked on Twitter two seconds ago. Many. And I really think it was the very first internet rumor. And because of that it doesn't die. Reporter: Fred savage would leave acting behind, get an English degree from Stanford, and become a director of such TV series as "Modern family" -- I'm kind of doing what I always wanted to do. From when I was a little kid. I'm very lucky. Fred, you're one of the best actors I've ever worked with, for sure. And if you ever wanted to act again I think you should because you're awesome. ? Reporter: For a generation of boys, Winnie cooper embodied the girl next door. If you happened to live in paradise. I just would tell people, look, it was slow motion. It was the music. It was the whole setup. It was the narration, like lifting me up on a pedestal. Come on. I can't take a lot of credit for it. Reporter: In college she would co-author a groundbreaking math theorem. She and savage still hear from fans a little irked by the show's ever-wistful finale. Have a nice life. I got asked, why didn't Kevin and Winnie end up together? I would say at least three times a week. I'm heartbroken. You just watched the last episode. I'm like, you know, it's just a TV show. Reporter: I'm Chris Connelly for "Nightline" in Los Angeles. Got to love that Chris
