I would like to know what happened to the story behind Robin's doormat. If you remember in season 1 (i think in episode game night), Ted tells the story to Victoria about the re-return where Ted goes to see Robin after their first date. But before Ted does anything, while outside Robin's door, he throws up on her mat. By the end of that episiode, they show Robin checking her new doormat, probably gifted to her but Ted doesn't say who. So i want to know whether HIMYM explained that story or did they just leave it?
