The last two seasons of 'How I Met Your Mother' have left us with some pretty surprising twists about the bride and groom of the future wedding in which Ted supposedly meets the future mother.  Now, as  the (potentially) final season kicks off Monday, September 24, we're going to be spending a lot more time at that future wedding.  But of the two involved, who freaks out most at the prospect in the latest clip from season premiere "Farhampton?"

Barney Stinson may not be the one to worry about when it comes to 'How I Met Your Mother's future wedding.  Sure, the Barnacle is naturally eager to climb out the window of his own wedding, but that's just bachelor's instinct, right?  The real worry is when the bride starts having doubts about going through with the marriage.

In the first clip from 'How I Met Your Mother' season 8 premiere "Farhampton," we see exactly that as Robin calls Ted to her dressing room to inform him that she can't go through with the wedding!  But why would Robin prove unable to go through with it, when we know Barney to be the usual commit-o-phobe?  And what exactly happened ten hours later, as the start of the clip notes?

Check out your first look at 'How I Met Your Mother' season 8 premiere "Farhampton" below, and give us your thoughts on the new season in the comments!
