They really have found their stride. This FEELS like HIMYM but at the same time it's its own thing. NPH is great, as always, and it's an amazing progression for Barney. And you gotta love a Puss In Boots: The Last Wish reference.
I hate what would be a good episode because they completely forgot that Mia and Charlie's family went to dinner like, they make a joke about how the dad is so cheap he ran away from the check and in this episode he's not a wimp? Just doesn't make sense.
