Pillow Talk

I did something this morning and I feel guilty. I ripped the tag off of my pillow. The tag says, "Under penalty of law this tag not to be removed except by the consumer". I want to know what law. Where in the penal code is the law that deals with pillows? If there is a law, why? What makes a pillow more important than a sheet? Or a toothbrush? Who decided that the pillow is sacred? I want to research this question to know the rationale. I think that the law also applies to mattresses. Maybe it is called the "bedding law". I am holding on to the tag just in case the pillow police come knocking on my door. I can always sew it back on.
