"Kimmy Has a Birthday!" is the 9th episode of the Netflix original series, Unbreakable Kimmy Schmidt.
Kimmy's 30th birthday party isn't quite the fun celebration of adulthood she wants it to be. Titus promised Kimmy that he’d make a song for her, but instead he sings Firework (which Kimmy has never heard before). Logan And Dong get into a fight over Kimmy, which gets physical. Kimmy asks everyone to leave during the party. Kimmy eventually realizes that she had a fun 30th birthday!
