Should women use their sexuality to their advantage at work? That appears to be the theme of the next all-new episode of "The Big Bang Theory," which will cause a big rift between Penny and Leonard.

Penny's new job will cause more tension in her relationship with fiancé Leonard in the upcoming episode, which is titled "The Misinterpretation Agitation."

Last week, the couple faced challenges after Penny decided to sell the car that Leonard bought her because she has a new company car. Leonard insisted that Penny keep the cash that she got in exchange for her old car since it was a gift. However, Penny turned it down and accused her fiancé of being upset because she no longer needs his financial support. In turn, Leonard told her that she has control issues.

This week, the pair will bump heads when Leonard finds out that Penny pretends to be single at work in order to gain more sales.

In a sneak peek video, Sheldon tells Leonard that a doctor has shown up at Penny's doorstep with flowers after she apparently gave him the wrong impression at work. However, when Leonard confronts her about the situtation, Penny becomes defensive.

"What's the deal?" Leonard asks Penny in a demanding tone. "You take off your ring when you go to work?"

"No, I just put it on the other hand, and turn it around, and keep that hand in my pocket," Penny confesses.

"Why?" Leonard replies.

"Look, I make more sales if these doctors think I'm single," explains Penny, adding, "I did the same thing when I was a waitress."

According to the Inquisitor, the doctor pursuing Penny will be played by guest star Billy Bob Thornton.

From the looks of the official synopsis, sexuality will be an underlining theme in the new episode.

"The guys try to help Penny out of an awkward work dilemma. Meanwhile, Amy and Bernadette argue over whether or not female scientists should play up their sexuality, on 'The Big Bang Theory,'" it reads, reports Yahoo! News.

"The Big Bang Theory" Season 8, Episode 7, "The Misinterpretation Agitation," will air on Thursday, Oct. 30, at 8 p.m. ET on CBS.
