10. Penny became a bartender because her leg was broken
Sometimes when cast members undergo some sort of physical change, it’s written into the script. Other times, the writers find ways to hide it, like putting a character behind a bar so the audience can’t see her busted body part. And that was the case with Kaley Cuoco, who broke her leg when a horse stepped on it during a riding lesson. This forced the showrunners to disguise the injury by making her character Penny a bartender for a while.
