‘Big Bang Theory’ Stars Kaley Cuoco and Melissa Rauch Are Truly Floss-Challenged in Behind-the-Scenes Look (Video)

Stars of CBS sitcom attempt to learn a new dance move

Well, they say flossing is important. But it might take a little practice, eh, Kaley Cuoco and Melissa Rauch?

“Big Bang Theory” star Rauch shared a behind-the-scenes look at the CBS sitcom with her fans on Thursday, via a video posted to her Instagram account.

The video depicts Rauch and her co-star Cuoco on set, attempting to master the dance move that has come to be known as the floss.

“Attempting” perhaps being the operative word here.

“Learning to floss with @kaleycuoco (I’m clearly nailing it) while taping tonight’s hilarious new @bigbangtheory_cbs episode!” Rauch wrote of the video.

Yes, clearly.

While the video suggests that Cuoco and Rauch still have some work to do, the duo received words of encouragement in the comments section.

“I don’t know how to do the floss either,” wrote one fan.

“It’s all in the hips. Get them going first,” suggested another commenter.

“Omg! I love this so much! I’m not the only one confused by this!!” read another comment.
