A man went into a deli shop and took a seat at the lunch counter. "Give me a corned beef sandwich," he ordered.
"Corned beef sandwich is not on the menu, but I can give you a sandwich with corned beef in it, like our Midnight Special."
"What's a Midnight Special?"
"A triple decker with corned beef, tongue, bologna, tomato, lettuce, onion, pickle and mayonnaise, on toasted raisin bread."
"Could you just place a piece of corned beef between two slices of white bread and serve it to me on a plate?"
"Why, sure!" Then, turning to the sandwich man, he sang out: "One Midnight Special. Make it one deck, hold the tongue, bologna, tomato, lettuce, onion, pickle and mayonnaise, and make the raisin bread white, untoasted!"
