This is the third episode with Chef's name mentioned in the title.
Chef's Islam name, "Abdul Mohammed Jabar-Rouf Kareem Ali" is a spoof of NBA basketball players Kareem Abdul Jabar and Mahmoud Abdul-Rauf, as well as legendary boxer Muhammad Ali.
The scene in which Chef sets the meditating monk on fire is a reference of Thích Quảng Ðức, a Vietnamese Buddhist monk, who burned himself to death in Saigon in 1963 to protest oppression of the governments position against the buddhist religion.
The brief flute passage that begins Wendy's dream sequence is lifted from "Prélude à l'après-midi d'un faune" (Prelude to the afternoon of a faun) by Claude Debussy.
Current Event/Georgia Flag:
This whole episode was probably a jab at the controversy over Georgia's state flag. That state flag contained the flag of the confederacy as part of its overall makeup. People wanted the state flag changed, as they felt the confederate flag still represented racism and slavery.
