Outdoorsman and writer Euell Gibbons famously said that the naturally sweet flavor of Grape-Nuts cereal "reminds me of wild hickory nuts."
The implication, of course, is that he had eaten wild hickory nuts and that, by extension, you almost certainly hadn't. Which is true, at least in my case.
Gibbons' whole schtick was that he went around eating nuts and berries and God knows what else that most of us would never even think of eating, and that they were nutritious and delicious — even if they didn't remind him of popular breakfast cereals.
