"It’s exactly what you’d think a burger with a donut bun would taste like." - Dodge (Seeking a Friend for the End of the World)
In Supernatural, Dean offers a variation of this burger called to Sam, contending that only inferior versions use a single donut for the bun (as opposed to a donut on the bottom and a donut on the top). He calls his version The Elvis. This is presumably a reference to singer Elvis Presley, who was known for eating extreme foods (like deep-fried peanut-butter-and-banana sandwiches) toward the end of his life.
However, the Luther Burger - a bacon cheeseburger served on a donut bun - is actually named after R&B singer Luther Vandross. It's unknown whether Vandross actually liked these things, but it was at least named to honor him.
