All of these were done for Yuletide - although not all may have been for 2007. All are Barney/Robin - especially the first two - but the last one hints at an undercurrent perhaps, although it is definitely rated PG.
Go Where Life Takes You - Barney, Robin, Ted, a bet, drinks, conversations, bathing suits, seasons and laser tag. Plus some lasagna.
Leave No Man Behind - For two people who weren't planning to ever get married anyhow, this marriage of convenience seems like something close to perfect.
Suit Up - Robin was so looking forward to a quiet night.
I recommended a few other Barney/Robin fics ages ago at my regular journal that I would be more than happy to post over here if there's anyone here who enjoys this sort of thing. Let me know if you have any interest in that. :)
