When my sister and I were in elementary school, many years ago, and my brother was not even in school, we would celebrate April Fool's Day by coming home at lunch and putting on "Fool of The Year" by Georgia Gibbs. Then, we'd point at my brother and say "That's you! That's you!". He would go nuts, really. We laughed hysterically until my mother had to come and break it up. He still remembers. At least he says he does.
I tried to find the lyrics; they're not on the web. But, I remember them fairly well. "I'm the fool of the year, I'm the fool of the year, for falling in love with you. I was taken by surprise by that look in your eyes and now, I'm the fool of the year."
