Kaley Cuoco discussed how she would like "The Big Bang Theory" to conclude and how it felt when the cast decided to end the series while appearing on "The Late Late Show."
"The stairs have gotten more and more exhausting as our seasons have gone on," she continued.
"The Big Bang Theory" is set to end with Season 12 which premieres on CBS on Monday, Sept. 24 at 8 p.m. ET before the show moves back to its regular Thursday time slot at 8 p.m. ET on Sept. 27.
"It was definitely tough," Cuoco said about deciding with her castmates that Season 12 would be the last season.
"It wouldn't have mattered when it ended, we all would have been completely devastated," Cuoco said.
"It's time now, I guess, to move onto other things, which is so heartbreaking."
The segment involved the trio acting in a dramatic soap opera with every line of dialogue consisting of lyrics from Drake.
