The veteran was a guest on former child star Gilbert's U.S. daytime show The Talk, and they opened Friday's episode sitting on their Roseanne couch as they reprised their roles as Dan Conner and his daughter Darlene, now all grown up.

In the comedy sketch, a flannel shirt-clad Darlene tries to broach a sensitive subject with Dan as he watches TV.

"So, uh, there's something I've been wanting to talk to you about for a while now," she begins. "I don't know how to say this... I'm a talk show host."

Goodman, as her dad, responds, "As long as you're happy, me and your mom'll support ya (sic)."

"You know, for a minute there I thought you were going to tell me you were gay," he quips, as Sara, who is a lesbian in real life, breaks out in laughter, along with the studio audience.

"Let's save something for halftime," she smiles as the bit comes to a close.

Goodman later joined Sara and her co-hosts for a full interview, and gushed about how much fun it was to reunite onscreen.

"I thought that was pretty amazing," Sara smiled, as John nodded in agreement and said, "That was like, way too easy! It felt like no time (had passed), which is really spooky!"

Goodman's character died in the series finale, which originally aired in 1997 at the end of the ninth and final season of Roseanne, but if creators could find a way to bring Dan back to life, he wouldn't hesitate to star in a reboot of the hit show, which also featured Connor TV matriarch Roseanne Barr.

"Oh, hell yes!" he replied when asked about a potential Roseanne comeback. "The big R (Barr) and I did a pilot (comedy) about five years ago that didn't go anywhere... but we were very happy working together, and I talk to her every once in a while. If we could get everybody together..."

Sara was a little more cautious, explaining, "Your only fear is you don't wanna do a bad version, right? Because you don't wanna damage what's been done, but I think it would be amazing. Just doing that (sketch) was so fun."

The Roseanne get-together wasn't the only reunion John enjoyed on Friday - he also got the chance to catch up with his The Big Lebowski co-star Jeff Bridges as Goodman was inducted into the Hollywood Walk of Fame.

Bridges, who donned the patterned sweater famously worn by his cult movie character The Dude as he delivered his tribute speech, joined Goodman's Kong: Skull Island co-star Brie Larson and Emile Hirsch at the grand unveiling of the 64-year-old's Hollywood star in front of the Hollywood Wax Museum.
