Romance is in the air! "The Romance Resonance" proved that even geeky guys can woo a girl when they put their mind to it. Howard's song was geektastic and oh so lovely, wasn't it?

Though, I guess the relationship turmoil from "The Workplace Proximity" was a distant memory as both Sheldon and Howard both on good terms with their ladies. Continuity has never seemed to be much of a concern to The Big Bang Theory writers. That may be part of the reason the show does so well in syndication.

Howard's decision to write and perform a song for his anniversary with Bernadette was a brilliant romantic gesture. It shows dedication and thought went into his gift and it didn't cost a thing. It was all about his love for his wife. Since this group of friends is so close with each other their inclusion just added to the heightened emotions.

His romantic overture led the others in relationships (Sorry, Raj.) to think about what they do for their partner. Penny desperately wanted to find a way to show Leonard how much she loves him. It was hilarious that she turned to the one person not in a relationship for help, though at the same time, Raj is usually the man to go to for grand ideas. 

His fixation on romance on film was fitting. I loved the references to Dirty Dancing and Say Anything. And, cooking definitely isn't Penny's forte as her ramen dinner proved. It was sad to see that after all the thought she put into the gift that it was such a bust. She even got rose petals. Rose petals and no sex! 

The experience proved that sometimes it's better for someone to just show their affection through their natural activities. Leonard was touched by the fact that Penny cared enough about him and their relationship to keep mementos of their time together.

Given the ups and downs of their relationship over the years, it was not only surprising but very romantic. It showed another side of Penny that we haven't seen before. And, for those that have questioned whether she truly loves him or not, here was the proof all in one box. It even had a bit of humor in there with the 11-page letter and pregnancy test. An unexpected, but immensely sentimental moment.

Then, there's Sheldon and Amy. I continue to be baffled by their affection-less romance. Amy clearly cares about Sheldon and is there for him physically and emotionally, but he rarely reciprocates in any manner. The final scene was over the top, so I didn't expect it to be real though I also didn't see the dream reveal coming either.

I wanted it to be real. I wanted Sheldon to finally want to kiss Amy, especially since the "mommies and daddies" line was so Sheldon. It ended up a big disappointment for Amy. At least she can image a kiss coming at some point in a Sheldon-like way. Until then she'll just have to stay in her own private zone.

In addition to the romantic theme, Sheldon also made a new scientific discovery that ended up being do to a mistake on his part. This provided a few funny moments and showcased Sheldon's inability to accept errors even though it brought him recognition within the scientific community. There wasn't any reason he had to let others outside his inner circle of friends know the truth. 

Sheldon's discovery may have been better suited for a different episode as it never really connected well with the romantic stuff until the very end when Amy said she was embarrassed for him. It was what he needed to hear. That moment didn't come across like she really believed it, yet she showed she cared in the best way that she could. And, her reward was to be added to his prized list.

The highlight was definitely Howard's song to Bernadette. It made me cry and laugh all at the same time. He sang about his love for his wife with references to Doctor Who, Klingons, and the perfect refrain, ""He'd probably still be living with his mom!" And, it didn't matter that she was quarantined behind glass. Their love for each other was unmistakable.

There were quite a few funny exchanges, check them out in our The Big Bang Theory quotes section. Here are a couple of my favorites:

Penny [to Sheldon]: Your food's ready.
Leonard: No, no, what are you doing? He's both happy and quiet. It's like seeing a unicorn and Bigfoot at the same time. | permalink

Sheldon: I feel like my mind just made a baby. And, it's beautiful. It's not like human babies which are loud and covered in goop. | permalink
