While I usually find The Big Bang Theory hilarious, this week's "The Pulled Groin Extrapolation" was a bit of a letdown.

Sheldon was basically alone with his toy train for most of the episode. His scenes are often the highlight of the show, but this was just dull. He's funniest when we are laughing at his interactions with others.

Another miss of the episode was Amy. Why did she stay with Leonard all night while Sheldon was out? I know she is quirky, but that was just weird and not funny. Well... the overstaying her welcome gynecologist joke was pretty good, but the rest was a snooze. That is the theme for the episode, unfortunately. I almost slept through it.

Even worse, Amy invited Leonard to accompany her to a wedding and he went. Really?!? That makes no sense at all. The only somewhat funny part of this excursion was the chicken dance... a chicken dance! The writers couldn't come up with something more original? The worst part of this experience was that Amy thought Leonard was falling for her in the end. Please, let that never come up again. The show will often drop stories after an episode and I hope this is one of those times. I don't want to see anymore Amy and Leonard stuff.

Did you notice though that Sheldon hit Leonard over Amy? Perhaps this wedding "date" will help Sheldon solidify his feelings for Amy and move their relationship forward.

The episode wasn't an entire loss, though, because Howard and Bernadette provided quite a few chuckles.

After Howard and Bernadette broke up and got engaged, I would have thought they discussed Howard and his unique relationship with his mother. It doesn't appear that ever happened. After all they went through that Howard thought Bernadette would move into his mother's house was very "Howard."

Everything seemed like it was going wrong for Bernadette during her trial stay at the Wolowitz home, but then... Bernadette turned into Howard's mother! What in the world was going on? I almost hope they do move into there because that would be an absolutely hilarious situation.

These Big Bang Theory quotes also saved the half hour was being a total downer. Browse and enjoy!
