Nuts and ...?

Have a look at this label. Pay close attention to the ingredients. See the last bit in brackets?

"(MAY CONTAIN TRACES OF NUTS & HARD OBJECTS)"

Okay, I applaud their disclosure that the product may have nuts, but can somebody tell me what the hard objects might be? Fingernails? Teeth? Bone? Screwdrivers? Hacksaws? Car engine parts?

After giving it some thought, I believe the hard objects they are referring to are bolts. I mean, that would explain their reticence to name the objects.

MAY CONTAIN TRACES OF NUTS & BOLTS

Yep, much better to call the bolts "hard objects".

I'm sure you'll agree that's the only things they could be. What could be more natural? Nuts & bolts. I mean, can you think of any other hard objects that could be associated with nuts?

Oh my. I'm going all red.
