'The Big Bang Theory': Almost perfect

bbt-feb9-cbs.jpgAfter a few weeks of deviating from the norm, "The Big Bang Theory" is back to where it should be, and we couldn't be happier.

[Spoiler Alert]

Sheldon ( Jim Parsons) is required by the university to take a vacation. To no surprise, the workaholic isn't terribly interested in taking any time off, mostly because he's emotionally and intellectually capable of processing such an activity. So he decides to spend the week working alongside Amy ( Mayim Bialik) at her biology lab.

"It's going to be romantic" she says, comparing their situation to Marie and Pierre Curie.

"Way to kill the mood," Sheldon responds.

While in the lab, Amy hands Sheldon the most mundane of tasks. Being the genius that he is, Sheldon is resentful of this. He ultimately acts completely inappropriate (in a Sheldon kind of way), which draws Amy's ire and some of his own blood.

In a well-fashioned subplot, Bernadette ( Melissa Rauch) is getting pressure from her father into securing a prenup with Howard ( Simon Helberg). But she's afraid to broach the topic with her betrothed. So the gossiping geeks share the news until it makes its way to Howard himself. The rocket scientist is nonplussed by this possibility and needs time to reevaluate their relationship.

Luckily for both Sheldon and Howard, Penny ( Kaley Cuoco) serves as the voice of reason. She tells Sheldon to go apologize. Penny also instructs Howard that he's lucky to have Bernadette and to sign the document.

When they both do as instructed, it's a tender moment showing emotional depth we rarely see from these characters. It's hard to remember a time that Sheldon has said he's sorry for anything. And Howard does a pretty good job at it too.

This episode offered it all. It had great laughs, sweet moments and balanced time given to each story line.

On a scale of 1-to-Pi, this episode was a 3.14158, or nearly perfect.
