More importantly— Who ever heard of a ham-and-cheese sandwich using one slice of bread?

A commercial, pre-packaged ham-and-cheese sandwich using one slice of bread is regulated by the U.S. Department of Agriculture, which conducts daily inspections under its jurisdiction, but a ham-and-cheese sandwich on two slices of bread falls to the Food and Drug Administration, which inspects plants about once every five years. That anomaly surfaced in the current presidential campaign and was verified by a Congressional Quarterly-St. Petersburg Times "Politifact" researcher in December.

A USDA official admitted to the Times that there "is no rationale or logic" behind the distinction: "(I)t's an issue that makes it look like we don't know what we're doing." [St. Petersburg Times, 12-11-07]
