‘How I Met Your Mother’ 100th Episode Coming Up

As hard as it is to believe that the comedy has been on that long, it’s indeed almost time to watch How I Met Your Mother‘s landmark 100th episode. The accomplishment couldn’t have happened to a “nicer” sitcom, either.

The big event will occur at 8pm ET on Monday, January 11, which also happens to be the series’ first fresh episode of 2010. Called “Girls Vs. Suits,” it features a predictable slew of guest stars, too.

Making an appearance for the very special occasion are The O.C.‘s Rachel Bilson as the character Cindy, Stacy Keibler of Dancing with the Stars as a bartender named Karina, and dapper Project Runway icon Tim Gunn cameoing as himself.

The plot goes like this: Barney serves as the inspiration for a sure-to-be-awesome musical number when he struggles to decide if his suits are worth giving up for the possibility of hooking up with attractive bartender Karina. And not to be outdone, Ted inches closer toward meeting the titular mother.

CBS is laying the videos on thick for this noteworthy episode, so check out all four below. The last one, The Cast’s Favorite Moments, is a particularly fun and long 4½-minute featurette. Apparently, there will be lots of suiting up committed by everyone.

How I Met Your Mother airs Mondays on CBS at 8pm ET.
