Chuck Lorre is simply brilliant.

Shamy is by far the most fun to watch.

Especiallysince Penny and Leonard are practically an old married couple.

The Romance Recalibration

Penny misses the days when her husband used to woo her on a daily basis.

Is that too much to ask?

Penny finds sanctuary in a girls night across the hall.

Amy is extra pumped.

Hosting girls night at her place deems her the official leader of the group.

As they drink and snack, Amy praises Sheldon for his newfound goal of being more intentional with others.

Hes like her boyfriend in college, only this time hes real!

When Penny complains about Leonard phoning in integral parts of their relationship, Amy shuts her down.

Theres no bumming people out during girls night.

Across the hall, Leonard and Sheldon have a boys night.

When Penny returns home, Sheldon asks about her time with Amy and Bernadette.

He becomes irritated by her one-word answers.

Leonard warns him not to test his wife, which upsets Penny.

At least Sheldon is asking about her day.

A confused Leonard looks on as Penny berates him for taking her for granted.

The next day, Leonard and Penny watch as Amy and Sheldon share a passionate goodbye kiss.

My, have these two come a long way from tight-lipped pecks!

Was that Amys leg I saw wrapped around Sheldons body?

The uncomfortable PDA morphs into an adolescent game of who will miss whom more.

Penny jerks Amy away from Sheldon and forces her into the hallway.

Sheldon notices Leonard is sad.

Its not that hes stopped trying in his marriage.

The infatuation has transformed into a mellow comfort.

He feels the same way about the Pythagorean theorem.

This annoys Penny, which in turn annoys Leonard.

Neither knows what they want.

They need structure and a plan.

Enter: The Relationship Agreement.

It may not include a bathroom schedule, but there is an entire section on scenarios requiring pants.

In other news, Halleys floor squeaks in her nursery.

Howard and Raj brainstorm how they can get to Halleys crib without touching the floor.

The guys end up mapping out the room in a grid-like fashion.

They determine the squares that are squeak-free and are eager to demonstrate to Bernadette how simple bedtime will be.

No need to worry about doing all that while holding a newborn baby in the dark.

The grid is made of glow tape.

MIT graduates think of everything.

Howard: I have to get Halley hooked on TV or one day shell want me to play outside.
