“It was a feel-good silly show, and these guys really were the heart of it,” Cuoco said. “They made the nerd thing cool and popular and sexy and fun. It was silly and people loved it. And I really loved my time on it.”

Summary. Kaley Cuoco cut her hair in season 8 of The Big Bang Theory for her role in the film Burning Bodhi. Fans were upset that the show didn't explain the haircut, but it was later addressed in season 10 through Amy's jealousy.

At the start of TBBT season 8, Penny sported shorter hair and a more professional look. She quit acting after having little success and for just not being any good. Jobless and low on cash, her friend Bernadette got her an interview for a full-time job, and after accepting that position she never went back to acting.

When returning to the series, she was shown working as a bartender instead of waitressing at her usual workplace, The Cheesecake Factory, to hide her injury.
