Anything to do with sweet potato. I once got tricked into eating a few sweet potato fries. I was sick for 20 minutes. Please don't put sweet and potato in the same name. It's wrong, weird, and nasty. If it's sweet, it's not a potato. If it's a potato, it's not sweet.
Samwise Gamgee did not say: "Po-tay-to. Boil em, mash em', put 'em in a stew, use 'em as a substitute for a candy bar."
Ick.
