Jim Parsons has such a warming smile. It’s a pity he couldn’t smile in the actual show.

If sheldon was real I wonder how annoyed he would be at jim Parsons for forgetting the science things

Two things: How Jim laughs and how Simon never messes up his lines🥺

The “did I get you” from mayim when she made Jim laugh made my heart melt

No message
    No Note
         No Line ...

PLEASE. The best part was Burt's line "I don't really have dreams. ... In sleep or in life."

"I always dreamed of working with Kathy Bates."
"Bite me."

Jim had the hardest lines because he had all of that science to memorize. He did an amazing job sounding so confident

Please I may be scared of butterfl- butterflies what?! 🤣

Wow, Howard never mess up!

I love that laugh😂😂

I just LOVE Jim Parsons.

oh my god, kunal's laugh when he messes up a line is my new favorite thing.

It's always dreamed of working with Kathy Bates! XD

I love it when Mayim laughs.

Her whole face lights up.

Personally, I am so glad that "The Big Bang Theory" Season 12 bloopers has finally arrived on YouTube! They have made me love and enjoy the TV sitcom even more than ever!

Johnny: "I'm not really loving my work right now."

Me: wow, 12 years of it.

Johnny Galecki is such a chilled out actor.. So much ease.. ❤️

5:45 thats melted my heart
