OK so overall, I thought this episode was OK. Not the worst, but not the best. It was good to finally meet the Slutty Pumpkin, and to learn that Barney is (part) Canadian.
Anyway, so the whole Marshall and Lily moving to the suburbs was kind of a copy of Friends, (how Chandler and Monica moved to the suburbs when a baby was on its way + Lily's grandma is the same actress as Monica's Mom) but it's good how they eventually didn't, I mean they did have an apartment.
The Barney and Robin thing was one of the good things about this episode (though Robin's hair looked absolutely horrible.)
What sucked about this episode is that Nora wasn't in it.
:( I am a Nora and Barney shipper, while Sam is a Robin and Barney shipper.
