Phoebe Buffay [SEP] "Smelly Cat"
The show's running gag and one of Phoebe's trademark characteristics is her song "Smelly Cat", which she performs at Central Perk. The song is about a cat who is shunned by society because of its foul stench as a result of flatulence ("What are they feeding you?"). However Phoebe sympathizes with it because she can relate to being an outcast. The verses consist of Phoebe rattling off a list of ways in which the cat is disliked ("They won't take you to the vet", "you're obviously not their favorite pet", etc.) while the chorus ends with the uplifting message to anyone who is different or unique that "it's not your fault".
