"Alternative" Uses of Quotation Marks

I saw a sign where one phrase had inappropriate quotation marks, but I didn’t remember which one after walking by. Before going back, I offered up these options:

“all natural” Bavarian roasted nuts – not really all natural
all natural “Bavarian” roasted nuts – not really Bavarian
all natural Bavarian “roasted” nuts – not really roasted
all natural Bavarian roasted “nuts” – not really nuts

It turns out that they were not really Bavarian.
