Underneath all the blond ditz and the hippie attitude, Phoebe Buffay (Lisa Kudrow) is by far the most street-wise and hardened character on Friends. Phoebe's backstory includes everything from her mother taking her own life to her father abandoning her to contracting hepatitis in the most unusual of ways.
Unlike the rest of the crew, Phoebe did not have a stable childhood. She was living on the streets of New York City by the age of 14 and never even had the opportunity to attend high school. And because she doesn’t possess a filter, Phoebe will often casually blurt out disturbing details about her upbringing.
Though Phoebe eventually found a group of friends who became a makeshift family, these messed up details of the years beforehand paint a much darker picture.
