The deals also include larger pieces of the show, signing bonuses, production deals, and advances towards the back-end.[37] Helberg and Nayyar were also able to renegotiate their contracts, giving them a per-episode pay in the "mid-six-figure range", up from around $100,000 per episode they each received in years prior.

Raj meets with the woman his father set up for him, Anu. Her commanding personality and practical approach to marriage startle Raj but he agrees to go ahead with it.

To get his mind off of it, Penny rents Leonard a Batmobile to drive in and have fun with for the day.

It’s no secret that the cast of The Big Bang Theory gets paid out for every episode. But, who is the richest Big Bang Theory cast member?

In the apartment building where Sheldon, Leonard and Penny (and later Amy) live, the elevator has been out of order throughout most of the series, forcing characters to have to use the stairs.

The Season 3 episode, "The Staircase Implementation" reveals that the elevator was broken when Leonard was experimenting with rocket fuel.[89] In the penultimate episode of the series, the elevator is returned to an operational state, causing Sheldon some angst.
It was really hard to pick the right pic for this post, so here is a shot of us in a hug after we filmed the last group scene we would ever film for the series... and TONIGHT is THE NIGHT... it’s the series finale at 8pm EST and then there’s the Young Sheldon (season!) finale, and then a special behind the scenes show hosted by @kaleycuoco and @sanctionedjohnnygalecki and then the entire cast is on @colbertlateshow I hope you get a chance to tune in and i hope you enjoy all of it. If you enjoy it even half as much as we’ve enjoyed (LOVED) creating this show for the past 12 years, then that’ll be a WHOLE WHOLE lot of enjoyment. All of us will miss seeing you in this format, but we will be around in all sorts of ways, I assure you... love love love ❤️❤️❤️
Well done! Really great final episode writing. The characters we have enjoyed for 12 seasons went on with their lives. . .but reached a happy place at that moment of time. Amy and Sheldon recognized for their brilliance. Penny and Leonard growing into a family. Bernadette and Howard being concerned about the children. Raj having someone fun to attend the ceremony with. Way to tie things up on a pleasant note.
