6+ Behind-The-Scenes Pics From The Final 'Big Bang Theory' Episode That Have Us Sobbing

Well, folks, The Big Bang Theory had an amazing run. But sadly, all good things come to an end.

As the cast wrapped up their very last episode ever, things got pretty emotional — and I can't say I blame them!

If you thought their final table read was emotional, brace yourself, because this is was even more of a tear-jerker.

After the cast ran through their final table read, things got super emotional.

But this was a walk in the park compared to their final taping.

Mayim Bialik took to Instagram as well to share her farewell to the show.

She posted a video, along with the caption: "It is an overwhelming day to say the least. All of the feelings: gratitude, sadness, joy, excitement, grief...it's the end of a huge part of our lives and the beginning of who knows what. Thank you to the millions of people who love this show. Thank you for the lessons we have learned from you all.

Thank you to our writers for caring so very much about these characters you all believe in and trust. Thank you for making our family a part of your family's laughter, tears, and challenges. I get to play dress up for a living and I am so honored to be a part of this cast, this crew, this staff, and this wonderful show about how these brilliant characters live, think, and love. It all started with a big bang."

"You know you work with wonderful and extremely thoughtful people when they celebrate your June birthday along with today’s birthdays (@kunalkarmanayyar @sanctionedjohnnygalecki ) because you won't be together when it comes around this summer," she wrote.

That is some serious dedication!

"So much gratitude for all the scenes I got to do with @kunalkarmanayyar. He is both one of the silliest men I have ever known and one of the most compassionate. If you follow his insta (and I can't imagine you don't) then you know. He just wants everyone to be happy. And to laugh. Working with him for 11 yrs has lead to much of both," he wrote for Kunal Nayyar.

"I will always be grateful for @sanctionedjohnnygalecki ’s warmth and generosity - I came onto the show when it was already a well-oiled machine, and he welcomed me with a warm hug and a cold smoothie," he wrote.

"Such an amazing talent, and in the land of Hollywood weirdos, just a genuinely nice guy."

He posted this selfie of him and Kaley, explaining in the caption that they were trying their best not to cry here.

"Do @kaleycuoco and I look like we’re keeping it together? Took this right before our final speed read. Before our final taping. Before my final emotional breakdown. Gonna miss working with Kaley so much. Sometimes you get to work with an actor that's so thoroughly in the moment that you can look to them at any time to ground you - Kaley has been that for me for eleven years," he wrote.

Jim Parsons posted this photo of his apartment door from the show on Instagram, along with a heartfelt caption.

"knock, knock, knock, thank you... Thank you, apartment 4A, for being a home to so many dreams come true, to so many friendships made. And thank YOU, ALL of you - yes, YOU, reading this right NOW! As we get ready to tape our final episode tonight, to walk in and out of this apartment door for the last time, it is hard to find the words to articulate what a profound experience this has been. But the words “love” and “gratitude” come to mind... so love and gratitude to all of you. ALL of you. Thank you," he wrote.

But Kunal Nayyar's post had to be the most emotional of all.

"Thank you Thank you for your words

Thank you for your encouragement Thank you for tuning in night in and night out

Thank you for the stories you shared about how this show made you feel

Thank you, for lifting us up when we were down

Fame can feel like a cage, so Thank you for making us feel safe enough to be free.

Thank you for letting me share my birthday on stage with my six best friends, And Thank you, for you, because without you- there would be no us. So this goes out to you, the fans... One last time," he captioned this photo.
