Underneath your clothes
There's a man that's horny

The story:

I think I was in middle school. Every time the song would come on in the car, I'd sing those words and my sister and mother would never bother to tell me that I was incorrect... I love to sing, and I was hanging out with some friends who shared the same interest. Of course, that song came on the radio. Obviously I had to start belting the words, and I'm pretty sure one of my friends busted an artery laughing. *hides*
