Kyle Richards Reveals His Favorite Watch Worth $270,000 And Its Surprising Owner During Live Event, You Won't Believe Who It Owns!

'The Real Housewives of Beverly Hills' star has sat across from host Andy Cohen dozens of times

Kyle Richards has many fond memories of Watch What Happens Live, and one stands out in particular.

PEOPLE caught up with the only remaining original Real Housewives of Beverly Hills star, 55, at the Posse Pride Party last Thursday, June 6, and asked her which of her many appearances on the late-night Bravo talk show hosted by Andy Cohen is her favorite.

Over the years, Richards has appeared in the WWHL Clubhouse alongside stars including Chloë Grace Moretz, Simon Baker and Molly Shannon. But her favorite memory was when she stopped by with former RHOBH costar and one-time frenemy Camille Meyer (formerly Camille Grammer).

"Oh my God, there's so many," Richards reflected. "But the one time when Camille and I played each other and re-enacted our iconic scene in N.Y.C., that was a fun one."

Richards was referring to a WWHL appearance from eight years ago where she and Meyer participated in "Clubhouse Playhouse," a recurring skit where guests re-enact iconic scenes from Bravo shows. In their case, they were asked to redo their season 1 fight (circa 2010) where Richards uttered the infamous line, "You're such a f--king liar, Camille."

The twist this time was they donned wigs and played each other. Watch the skit below:

"I'm a horrible blonde, Andy," Richards quipped.

"And I'm a terrible brunette," Meyer added.

Nowadays, the two reality TV stars get along, with Meyer making frequent appearances as a "friend" or guest" after exiting the show after season 12.

Speaking of frequent, according to IMDb, Richards is the most frequent guest on WWHL with 36 appearances over the years.

However, at the WWHL 15th Anniversary party last week, Cohen said that The Real Housewives of New Jersey star Teresa Giudice was "the most common guest" with 42 appearances. (IMDb lists her at 34 appearances, tied with RHONY's Sonja Morgan.)

PEOPLE also asked RIchards' RHOBH castmate Garcelle Beauvais, what her favorite WWHL memory has been in her 15 appearances.

"My favorite part is just getting to the studio," the former model, 57, said. "It's so much energy, it's so great. Andy [Cohen] comes in and he says hello. Sometimes we do shots. It's fun, it's really fun! I love it there. I wish I could've gone to support [the anniversary] but we were working."

Cohen himself echoed Beauvais' sentiments during a Tribeca Talks event with Anderson Cooper on Wednesday, June 12.

"My show is, can be like a fishing expedition where I’m sitting there and I will see a question on a card and I'm like, 'Oh, that's kind of interesting. I'll ask it,' and it will unleash something so exciting. It's like a Pandora's box," the host explained. "And then my endorphins start going and then it becomes a big story the next day. It's very exciting."
