LOS ANGELES, March 21 (UPI) -- In The Comeback Season 3, premiering Sunday at 10:30 p.m. EDT on HBO, Lisa Kudrow returns to the Warner Bros. lot and the very stage where she filmed Friends. On the show, Valerie Cherish (Kudrow) stars in a sitcom written by AI

The AI storyline is speculative, but the fictional sitcom films on Stage 24, which housed Friends from 1994 - 2004. At a recent Los Angeles press conference, Kudrow, 62, said it was inevitable The Comeback would finally reference Friends.

"Couldn't help it," Kudrow said. "We were shooting on the Friends stage."

The first joke is that Valerie ignores the legacy of Stage 24. A real plaque on the exterior lists all the movies and television shows that filmed there in the history of Warner Bros.

"She was only looking at the movies on the plaque," Kudrow said. "She didn't even see the TV shows and just like, 'We're going to be the first hit for Stage 24.' Right, Friends was a hit, Mike & Molly and whatever else you see there."
