Work That Fat is an unreleased song recorded at some point in 1991, most likely at Paisley Park Studios in Chanhassen, Minnesota (although possibly at Larrabee Sound Studios in North Hollywood, California). The comical song uses backing music from Martika's Kitchen, and was possibly recorded around the same time, in early 1991. Prince uses a slowed-down voice throughout the track (not dissimilar to that used on Bob George), and the narrator describes a date with a fat girl who eats everything in sight in the narrator's apartment (similar to the Exodus album segue commonly known as the "Mashed Potato Girl" segue).
Regardless of the disastrous date, the narrator likes his women "fat 'n' proud, cause when they sit down they sit all around, the whole house, sidewalk and everything else." It is not known if the song was intended for his next album Diamonds And Pearls or any other project, although given the distorted vocals and the comical nature of the song, it was probably thought of as a side project of some sort, and if it had been released, it may not have received the artist credit "Prince".
Both Sonny T. and Mike Scott are called out by name during the song. Mike Scott would later go on to join 's band, but this is believed to have been his first appearance on a Prince-related recording.
