The Big Bang Theory finale taping is one of the most historic nights, as it marks the last chance seeing the entire cast in front of the live audience. The night was a very memorable moment for everyone, including fans, crews, as well as the cast, and here's what they think about it.

During The Big Bang Theory finale taping on Tuesday night, the cast and crew prepared for the hit American sitcom's last filming, which is the 279th episode. Moist eyes can be seen everywhere, such as Johnny Galecki (Leonard) and Kaley Cuoco (Penny) whom both appeared misty-eyed. There were also frequent hugs before the "action" was said to film the final episode.

That night, Galecki, Cuoco, along with and Kunal Nayyar (Rajesh) took turns on the mic and thanked the audience. The rest of the cast also got caught in the moment, such as Simon Helberg (Howard), Melissa Rauch (Bernadette), Mayim Bialik (Amy), as well as Jim Parsons (Sheldon). During the cast introduction, some of the sitcom's stars can be seen wiping their tears while they took their bows.
