A teacher calls her first grade class

from recess. She goes up to little Sally and asked, "Sally, what did you do at recess?" "I played in the sand box." "Good. Now, if you can spell the word 'sand' on the black board, I'll give you a fresh baked cookie." So she spells the word right and gets a cookie. Then comes in little Billy. "Billy, what did you do at recess?" "I played in the sand box with Sally." "Good. Now, if you can spell the word 'box' on the black board, I'll give you a fresh baked cookie." So he spells it right and gets a cookie. Then comes in little Mohammed from recess. "Mohammed, what did you do at recess?" "Billy and Sally threw rocks at me!" "Hmm, that sounds like blatant racial discrimination. If you can spell 'blatant racial discrimination', I'll give you a fresh baked cookie."
