Phoebe Buffay is remembered as Friends' most unconventional character, and several of her bizarre storylines became iconic; however, one of them could never have existed without a real-world change to Lisa Kudrow's life. Phoebe is a Pandora's box, and the beauty of her character lies precisely in the fact that anything is possible with her.
