Yes I do! I've started a small collection of labels that are fishy. I'll start with fish. :
Trader Joe's "Smoked Herring" (comes in a flat can) has an ingredient label that reads "smoked herring, salt". But when you open the can, it is obviously packed in oil. My guess is that it is soybean oil, but since it is not identified on the label, it could be anything.
Another is Trader Joe's sprouted multi-grain bread (no wheat). The calorie counts don't add up and I don't think such a think slice of bread could have only 4 net grams of carb.
Another is Campbell's soups. I keep a couple of cans on hand just in case one of us gets sick when our kids are sick. Those labels never seem to add up.

I'll have to check my label collection & see if there's more. The hiding of trans fats seems to be the more popular issue these days.
