The kindergarten class had settled down to its coloring books. 

Steve came up to the teacher's desk and said, "Miss Merc, I ain't got no crayons."  

"Steve," Miss Merc said, "you mean, "I don't have any crayons. You don't have any crayons. We don't have any crayons. They don't have any crayons. Do you see what I'm getting at?"
 
"Not really," Steve said, "What happened to all them crayons?"
