Jimmy came home from school with an F on his geography test. His mother was reviewing his work, and noticed that he had gotten one particularly easy question wrong.
"Jimmy," she asked, "Santa Cruz is in California."
"No, it isn't. It doesn't exist."
"Of course it exists. What makes you think it's imaginary?"
"That's what you told me, mommy," the boy replied.
"When did I tell you that?"
"Last Christmas, when I wanted to know why I didn't get a horse."
"No, I told you that Santa CLAUS doesn't exist, not Santa CRUZ."
