Green’s Daryl has a surprise in store for his cronies. The catch? It’s located in the depths of hell (i.e his spooky basement). “Can we just see it in the living room,” begs Marshall. “Anywhere less gimp storage-y?”

  • Am I the only one that thinks Patrice is helping Barney propose to Robin?

    • I’m pretty sure that’s the case, too. Their behavior is odd, and there are plenty of weird throwaways that make it seem like it’s definitely a plan. (Barney purposely not looking in the closet while reaching for things or throwing his shoes in? Making ridiculous statements about not leaving the apartment, or purposely leaving with Patrice to go downstairs at the end? And when they’re out on the balcony arguing, we don’t actually hear what they’re saying.) I’m sure it’s a ruse meant to force Robin to admit her feelings.

  • Ugh, I can’t watch this show anymore. I want to tune in for Seth&Alyson, and I want to know what happens when it ends, but I just can’t watch regularly anymore. &Maybe I’m crazy and remembering it wrong; but it looks like Stellas basement. Maybe it is?

    • I know that was the first thing I thought they must only have one basement set and just re-dressed it, lol.

  • Why is he wearing German flags on his jacket? More stupid stereotypes? Just what this show needed…

    • I have that same jacket, it’s a label or something

  • It kind of sounds like I’m one of the few into this show anymore. To be honest, I watched the pilot episode and hated it, then didn’t watch it again until season four, then went back and watched every episode within a week. I even re-watch ALL of the previous episodes now every so often! Granted, I kind of disliked season 6 with the exception of a few episodes, but I’ve thought last season — and this one — were excellent. It’s become one of my FAVORITE comedies on TV, if not the very favorite. To be honest, the fourth-wall thing is a little odd for sitcoms, and I would despise it in a lot of shows… but considering the way the story is being told, as a father describing old experiences (many that he wasn’t even there for) to his children, it kind of works. It’s not like we can expect it to be totally realistic… after all, it’s taken Ted almost eight years to tell his kids how he met his wife. It honestly sounds like it will be a fun scene taken out of context when the dude retells a story to his kids that he wasn’t there for almost twenty years later. And Patrice helping Barney to ask how to propose to Robin??? I NEVER THOUGHT ABOUT THAT! Damn, maybe I am a horrible TV reviewer (and apparently good watcher…) but that sounds about right. We may know that Barney and Patrice are getting along as friends… but they’ve never kissed on-screen… I may have to re-watch the past few episodes to check out this theory! …Just for research. Not for fun, of course! :)
