Improv-ed Jokes
Some of the shows’ funniest lines weren’t even in the original script! For example, when Ross starts dating his student, Elizabeth, he told her: “I can’t stop thinking about your dad,” and then the writers decided on the spot for her to respond with: “Well, whatever works for you!”
Art Imitates Life
Whenever Ross would start discussing Paleontology, the group would quickly pretend to fall asleep, out of boredom. This was added into the show because the six main members of the cast would actually pull this exact move on each other in real life if they thought someone was being boring!
