Matthew Perry and Lisa Kudrow wish "Friends" could keep going

It's been almost 10 years since "Friends" went off the air, but at least two of its stars are still missing the hit sitcom.

Matthew Perry and Lisa Kudrow reminisced about the series during an appearance on "Piers Morgan Tonight," even saying they wish they could go back in time and keep the show going.

"I find myself sort of reminiscing about how much fun the show was, and the hours that we worked. You can see how much we laughed and everything," Perry, 43, said Friday, while guest-hosting the CNN show. "And I found myself saying, 'If I had a time machine, I would like to go back to 2004 and not have stopped.'"

Kudrow, 49, who now stars on the Showtime series "Web Therapy," agreed. "If it were up to us, you know, individually, then yeah. I would keep going," she said. "There would have come a time anyway when someone would have said, 'We've had enough.' But why not have fun until they do?"

"We were a part of something special," Perry noted. "And, we were very grateful the whole time. But I think just in that, in that meeting where we all said 'let's stop,' I probably would have said, 'hey, let's not stop.'"

The actors were also asked by CNN producers to pick their favorite moment from "Friends," and they both ended up choosing the same one -- when Phoebe and Chandler are about to kiss and he admits he's in love with Monica (played by Courteney Cox).

"That was hilarious," Perry said of the clip. "I forgot how much fun we were having."
