Birthday (song)
In one version of the music video for "Birthday", Perry dresses up as five different characters attending various birthday parties.  They are Goldie (a burlesque dancer), Kriss the Clown, Yosef Shulem (a rabbi/DJ), Princess Mandee, and Ace the Animal Trainer. There is a link to this version of the music video on Katy Perry's official website. All five characters can be seen in the video.
