How I Met Your Mother Films a Musical Number

The cast of How I Met Your Mother suits up for the show’s 100th episode, “Girls vs. Suits,” which will end with a legendary musical number!

In the episode, Barney, played by Neil Patrick Harris, has the chance to romance a beautiful bartender, but she doesn’t like guys in suits!

The ensuing musical number, “Nothing Suits Me Like a Suit,” features 65 dancers and a 50-person orchestra – and, of course, the HIMYM cast!

“It almost felt like an old-school MGM musical to me. It was a lot of cast and crew grouping together to make it special,” Neil told USA Today.

HIMYM‘s 100th episode airs Monday, January 11 at 8/7c on CBS!
