Chuck Lorre reached out to Thornton's manager with a simple yet heartfelt request of whether he would consider doing a guest spot on the show, for his mom. Without hesitation, Thornton accepted, saying that he would do anything for his mom.

Surprise cameos are hard to pull off, in the age of social media where spoilers are abound everywhere, especially while the show has been in production. The producers of The Big Bang Theory decided not to promote Thornton's appearance and aimed to keep it a secret until the episode aired.

Filming in front of a live studio audience added an extra layer of complexity, but somehow, they managed to keep it under wraps.

In season 8, episode 7, titled The Misinterpretation Agitation, Thornton portrayed Dr. Oliver Lorvis, a socially awkward urologist who developed an unexpected crush on Penny, played by Kaley Cuoco-Sweeting.

The twist was that Penny took off her engagement ring to increase her sales as a pharmaceutical rep, which caused some amusing misunderstandings.

Interestingly, Thornton had a plot idea for his character. He said he wanted Dr. Lorvis to have a brief love affair with Penny. The character did make a cute attempt to impress her, but it didn't quite work out. This dynamic gave the plot of the show, which is typically based on science, a delightful layer of complexity.
