The Pope's Nose

Does anyone know the origin of the term, "The Pope's Nose" or "The Parson's Nose" as it refers to a turkey's tail?

Don't know the origin, but a point of interest: in northern Africa, it's the "sultan's nose."

One meaning I have heard attached to the term is the fleshy tail of a fowl, particularly a turkey. It was used as a derogatory term by Protestants.

Interestingly, though, Italians, who are mostly Catholic, value the fatty appendage in soup making.
