Generally I don’t bother spoiler-tagging the network’s description of an episode, but this is one of those episodes where the premise is surprising enough to warrant it. [Think Shelter Island - there was no way to say "Ted and Stella's wedding" without it feeling like a major spoiler.] Anyway: Press release after the jump!
ROBIN AND TED DISCOVER THEY GET ALONG BETTER AS ROOMMATES IF THEY BECOME ‘FRIENDS WITH BENEFITS,’ ON “HOW I MET YOUR MOTHER,” MONDAY, JAN. 12
Heidi Montag and Spencer Pratt (“The Hills”), Playboy Playmate Kendra Wilkinson (“The Girls Next Door”) and Kim Kardashian (“Keeping Up with the Kardashians”) Guest Star
“Benefits” – When Ted and Robin become “friends with benefits” to deal with conflicts they’re having around the apartment, Barney tries to resolve the issues so they’ll stop hooking up. Meanwhile, “reality” stars get too real for Marshall when they taunt him from the pages of his magazine, on HOW I MET YOUR MOTHER, Monday, Jan. 12 (8:30-9:00 PM, ET) on the CBS Television Network.
Here’s a second episode description, which they’re using as the caption for the episode stills:
Robin and Ted navigate being exes who are now roommates and discover they get along better when they’re sleeping together as ‘friends with benefits.’ Barney is trouble by the news and has a hard time dealing with his emotions.
