"I'm sure I'll take you with pleasure!" the [White] Queen said. "Twopence a week, and jam every other day."
Alice couldn't help laughing, as she said, "I don't want you to hire me—and I don't care for jam."

"It must come sometimes to "jam to-day,"' Alice objected.
"No, it can't," said the Queen. "It's jam every other day: to-day isn't any other day, you know."
