How I Met Your Mother's final season is going to be legen  wait for it!  dary.

CBS confirmed on January 30 that the popular sitcom will return in the fall for its ninth and final season, according to TV Line.

And yes, it is during this final season when we'll finally meet this mysterious mom that we've heard so much about.

The entire cast has signed on for Season 9. 

“We‘re thrilled to have the entire and incredibly talented How I Met Your Mother cast back for one final season to bring the series to a proper close,” says 20th Century Fox in a statement.

Cobie Smulders, who plays Robin, says, "It'll be nice starting season nine knowing this is it. Soak it in. Really be grateful and enjoy this last year."

So while it will be sad for us to eventually say goodbye to the hilarious show, it's nice that the show gets one more year to wrap the story up right.

Plus, if the show went on for much longer, it would be weird to see Ted's kids sitting on that couch while middle-aged.
