Ms. Middler--the Tennessee Teacher--was giving the class a little three minute bit about cloning. The next day they had to answer a question about her three minute lesson. Comprehension. Memory. Content. Who knows all the things she gleans from their answers. We join her in the middle of her lesson on cloning.
Ms. Middler: "So, then the egg begins to divide, just like an ordinary egg."
Seventh Grade boy, waving his hand wildly in the air: "This is just like sixth grade..." and then he said the "M" word.
The whole class took a deep breath, including Ms. Middler. What on earth am I going to say to him, she thought. 
The boy kept talking--he's one of those talkers. By the time he ran down Ms. Middler had finally gathered her wits. "Did you mean sixth grade maturation?" she said.
The whole class, relieved that someone was going to address his mistake, burst into laughter.
The boy turned bright red. "Oh, yeah," he said. "I get those two words mixed up." And then he paused and said in a small voice, "I guess I shouldn't use those words until I can tell the difference, huh?"
