The Big Bang Theory Series Finale: GRADE IT!

It would have made for a very easy and cheesy opening to write that The Big Bang Theory went out with a bang on Thursday night.

But after 279 episodes, the final two of which comprised an hour-long farewell to the longest-running multi-camera sitcom in history, this description would be inappropriate.

The series instead went out with a bow...

... and it felt entirely appropriate.

We'll start with what many probably consider to have been the biggest takeaway and also the least significant:

The perpetually-broken elevator has been fixed! For real!

For 12 seasons, the elevator next to apartment 4A and 4B had been out of order and covered with yellow "caution" tape. But not anymore! It is back in business, folks!

Elsewhere, in perhaps even more exciting news, fans were stunned to learn that Penny and Leonard’s are having a baby!

The couple had previously decided against parenthood, but everyone's favorite girl-next-door and quirky scientist discovered they were expecting to close out their romantic storyline -- and weren't exactly disappointed about the news.

Unable to keep the pregnancy bombshell a secret, Penny and Leonard chose to inform Sheldon on their way to Sweden.

(Did we mention that Sheldon and Amy won the Nobel Prize for Physics? Hence this trip to Sweden? Because they did!)

“She’s clearly sick and I’m going to catch it and it’s going to ruin the greatest day of my life,� Sheldon told Leonard, focused only on himself in this moment.

“I promise you you’re not going to get what she has,� he replied.

“I’m pregnant, Sheldon,� Penny said.

“You’re right, I can’t catch that,� responded Sheldon... and that was it.

"You just found out that a woman you have loved and cared about for 12 years is pregnant and all you can say is you’re relieved she’s not going to get you sick? You are a selfish jerk," Leonard appropriately shot back.

Didn't seem like it was shaping up to be a very feel-good finale at this point.

Once everyone threatened to leave Sweden due to Sheldon's self-centered attitude, our hero had a somewhat life-changing moment.

He had a revelation.

And he altered his big Nobel Prize speech as a result.

“I have a very long and somewhat self-centered speech, but I’d like to set it aside,� said Sheldon. “This honor doesn’t just belong to me. I wouldn’t be up here if it weren’t some very important people in my life.�'

After thanking his family, Sheldon turned to his friends and said the following:

“My other family who I’m so happy to have here with us … is that Buffy the Vampire Slayer?�

(LOL! Yes! Sarah Michelle Gellar actually made an appearance in the finale!)

“I have been encouraged, sustained, inspired, and tolerated not only by my wife, but by the greater group of friends anyone ever had,� Sheldon continued.

“I apologize if I haven’t been the friend you deserve but I want you to know, in my way, I love you all.�

And that was it.

Low key and perfect, right?

The only thing more perfect? This Instagram photo of the cast on its last day of group shooting:
