Noah Veltman, a student of obscure government regulations, tells NPR: “My new home state of New York has a special tax category for sandwiches. And because they have that, it means they then have to go and define what they think a sandwich is. So they publish this memo that explains that a sandwich includes club sandwiches and BLTs, but they also include hot dogs and they include burritos and they include gyros. And then you have to sort of say, are burritos really a sandwich?” See also NPR’s follow-up podcast on the subject. (Hat tip to Paul Hsieh.)
