Ha! My father is a high school English teacher, and he sings If I Were a Rich Man every year in a futile effort to get kids to understand the subjunctive. Well, it worked with me, at least! I once collaborated on a legal brief once with someone in my law school class who flat-out refused to believe me when I pointed out his failure to use the subjunctive mood. He'd never even heard of it! Thought I was making it up!
