Sheldon, Amy, Leonard, Penny, Howard, Bernadette, and Raj decide to go away together on a trip. This togetherness may be the last straw for many in the group in dealing with Sheldon's self-centeredness. Meanwhile, Leonard and Penny have to decide when to divulge some big news, which they have not yet told anyone. This trip will mark the first time that Howard and Bernadette have left the kids for an extended period of time, Stuart and Denise who will act as their sitters. It may be more difficult than they imagined to be away from the kids, especially due to the distance. And Raj, in the absence of Cinnamon who is staying with Bert, meets a new friend.

Bernadette Rostenkowski: She fell down the stairs?
Stuart Bloom: [stammering] She rolled down the stairs, laughing the whole time. Anyway, when she got to the bottom, there was a tooth missing.
Bernadette Rostenkowski: Oh, Stuart!
Stuart Bloom: She's fine! She thought it was funny.
Howard Wolowitz: Did you at least save it for the Tooth Fairy?
Stuart Bloom: No, we couldn't find it. We ...

Perfect Farewell
17 May 2019 | by faeez_rizwanSee all my reviews

I've seen plenty of TV shows come and go but damn I'm going to miss The Big Bang Theory. I'm feeling really sad about this. The way it ended was beautifully directed and I think this series will stay in our heart for a very long time. Thank you for the past 12 years ✨
