It was recess and the pre-schoolers came in. The teacher asked Susie what she did today. "Well, I played in the sandbox, " she said. The teacher said, "If you can spell sand, I'll give you a fresh-baked cookie." So Susie did.
Then Billy came in and the teacher asked what he did. "I played in the sandbox with Susie, " he said. "If you can spell sand, I'll give you a cookie, " the teacher said. So Billy did.
Then the little Russian boy said, "Well, I wanted to play in the sandbox, but Billy and Susie were throwing rocks at me."
The teacher said, "Well, that sounds like discrimination. If you can spell that, I'll give you a cookie."
