Complex says: Who doesn't like the Bartman? Gucci's go-to chain while recording Back To The Trap House (2007) was so ingenious, he just had to write another chain tribute about it:

Gucci Mane "Iced Out Bart"
The song was eventually cut from his album for unknown reasons, but we're guessing they were trying to avoid a lawsuit from Matt Groening. They've got enough problems on their hands once, you know, Gucci finds out about him.
