I enjoyed this episode, it was thoughtful in the sense that it paralleled with reality: having partners who have similarities with our parents is very common - more common than we think. And yet, at the same time, it was funny too, when the characters are morphed into their partners' parents, especially when Lily was morphing into Marshall's dad.
'If Nora is even the tiniest bit like her, I'm a lucky guy.' This was my favourite line in the entire episode. Although the playboy Barney is missed, I love the changes that we are seeing through him. It's no doubt that he's always thought highly of his mum, but even hearing those words warm one's heart.
