One that I think mentioned here, is that Beard's wedding was not a dream sequence and Ted did not go to Beard's wedding. The way he described it is their relationship is one in which they can be together constantly and then not see each other for years, and then pick up like they never left. He imagined it as Beard had a short notice wedding, called Ted but Ted had to coach a game for Henry that weekend and Beards was like "cool, good luck!".
