12th grade English class. They had a guest speaker. The Marine Staff Sergeant had presented to many of the same students before, so he divided the class into two teams--the group that had heard him speak and the group that hadn't.
He made it into a game. He asked questions that anyone who had heard him speak before would have known the answer to. If they had been paying attention. Because of this, he gave the group who hadn't heard him speak first shot at answers.
The two teams ended up tying.
But that's not why I mention this.
He had the teams name themselves. Team heard-him-speak-before: White Lightning and Black Thunder. The team that hadn't: Ebola Gang.
Where do they come up with these things?
