I can only assume that that was one of Mr. Jones' favorite tricks, because he did it once in my choir class, too. Also, he later became principal of my high school and seemed to make it his mission to keep me from graduating. At first I thought maybe he was carrying a grudge because he'd seemed to hate me for no good reason in jr. high too, but no... he didn't actually remember me. I can only assume that he was just generally an evil, evil person.
