Maybe this is just me being lazy on a Monday, but I don't really feel like reviewing How I Met Your Mother on a weekly basis anymore. Aside from big things happening--like Robin and Barney getting back together, or Ted on the hunt for the Mother--I'm not really interested in whatever random thing is going on. This is mainly due to the fact that I don't care about Kevin or Nora. I don't find them funny and I continue to think they're plot devices being used to comment on the characters.
That said, "Noretta" had some funny moments when the parents replaced the significant others. It's a subject broached on plenty of shows, but HIMYM is a visual show and isn't afraid of putting the characters in very awkward positions.
