I just had a thought: If the show is "How I Met Your Mother", and he's supposed to be telling his kids the story of all the situations that led to meeting the mother, then the wedding we finally meet the mother should be Robin's wedding, not Barney's.
My thoughts for this is because we meet Robin in the pilot episode. At this point, Barney and Ted had already been friends for 4 years, and that would be a more natural starting point for the story.
Exactly. It will make the entire series make far more sense if it is Barney and Robin's wedding. We'll find out in a few weeks.
