The supporting actors of The Big Bang Theory, including Kevin Sussman, played a crucial role in the show's success. However, Sussman did not enjoy every scene he filmed. One scene in particular that both Sussman and Kunal Nayyar found underwhelming and disturbing was a hot tub scene.
Sussman disliked going underwater and found the hot tub to be dirty. Similarly, Kaley Cuoco was repulsed by a scene in which she was covered in hair. Despite these challenges, the cast persevered and delivered exceptional performances throughout the show's 12-season run.
