Ah, yes, most of us have been in a school classroom. Especially in middle school, some kids make the stupidest mistakes or mess ups. Some students believe in anything people tell them and say it everywhere.
I'll tell of a quick story: Our History Teacher makes us respond to a blog on the school website. One of our blogs was to say what was fascinating about WWI. One kid forgot to spell check and said in part of his answer "The Allies and the Untied states of America...."
Discuss any other stupid moments or messups in the classroom which made you facepalm.
