Fishy crackers

One day last year I was picking my son up from school and he told me that his belly didn't feel that well during the day and that he had been sent to the office. He then told me that the school secretary/nurse had given him sardines and he felt much better.
I asked him "sardines, are you sure?"
"Yes, Mommy the white crackers they really helped!"
I couldn't stop laughing... I said "Nol, those are SALTINES not sardines."
