"Big Days" is an awesome episode and amazing season premiere for season 6 How I Met Your Mother. This episode is a huge improvement from season 5. I love how Ted sees Cindy at the bar and she's with this woman who Ted assumes is her room mate. I love how it turns out that Cindy and this woman are lovers and that they got married and had a daughter. I love how Ted reveals that he met their mom at a wedding and it shows that Ted is the best man. I give this episode a 9/10.
