'How I Met Your Mother' creators tease 200th episode, what's coming in Season 9

himym-200th-ep-carter-bays-craig-thomas.JPGThe cast and crew of "How I Met Your Mother" celebrated the show's 200th episode on Thursday (Nov. 21). Amid the cake-cutting and words of praise for the show, creators Carter Bays and Craig Thomas revealed some of what you'll get to see when the episode airs in January.

"Our 100th episode ['Girls vs. Suits'] was very much a celebration of the cast. Not that the cast doesn't deserve celebrating even more after 200 episodes, but this one is a different kind of story," Bays says. "It's about the story. It was an episode we intended on doing anyway, and it just happened to fall on the 200th. ... But it felt like the right one to do in terms of the greater story of the show."

The episode is called "How Your Mother Met Me," and it will detail how the Mother ( Cristin Milioti) got to where she is now -- so expect to see references to the yellow umbrella, her time living with Cindy and other near-misses in hers and Ted's ( Josh Radnor) story.

Thomas also says that the second half of the season will feature more of Milioti, whose screen time has been somewhat limited so far. "We wanted to find the right balance when she appears," he says. "We like the idea that the audience tunes in not knowing if they'll get her. ... I don't want to say how much or how little [she turns up], because I like the idea that the audience doesn't know week to week. She'll pop up in some unexpected ways."

The latter half of the season will also feature more of the moving back in forth in time Bays and Thomas promised before the season started.

"There's an episode coming up that's set largely in China. That's real -- I'm not kidding," Thomas says. "There's an episode that's mostly flashback, and mostly set in China. That will make sense once you see it. But there are a bunch of episodes coming up where anyone having fatigue of the wedding weekend will be happy -- there's a lot of crazy, time-machine, structural jumpiness coming up that I think people will enjoy."

And slap fans, take heart: The poster hanging behind Bays and Thomas in the photo had every episode title printed on it, and according to that, episode 199 is titled "Slapsgiving 3: Slappointment in Slapmarra."
