Kaley Cuoco, the veteran actress who played Penny on "The Big Bang Theory," revealed that she only watches older episodes of the show. She refuses to watch newer installments as they are too emotional for her. Cuoco also mentioned that if she comes across an older episode while flipping through channels, she will turn it on, but not anything too recent. She hardly recognizes herself in those early episodes due to her character's frequent changes in hairstyle and clothing. Therefore, Cuoco is comfortable watching her earlier stints as Penny on "The Big Bang Theory."
