When an ancestry DNA test gets mixed up in the lab by a new intern, #Ted & #Meredith are given the news of a lifetime! You're the PROUD parents of your medical practitioner! Wait? What! But they never even HAD kids! Sure Meredith wanted kids but Ted was less inclined... But "junior" is married & has kids of his own? Ted turned over a new leaf learning he just became a grandpa! Jaymes & #Maaike couldn't bear to tell them about the mistake, so the kids get to visit #StrangerVille on the holidays.
