I am sorry for constantly being the guy with low scores for this show, but tonight's episode just wasn't funny. I laughed twice, maybe, and it was toward the end of the show.
Stuart being involved was a recipe for disaster I suppose, but the cliched girl getting drunk, destroying Penny, who was once a little bit different than your usual sitcom female, and not caring in the least.
At least the show is focusing on Sheldon and Amy. That's wise, but one of the few things to applaud about this episode tonight.
