I cannot not hear the first lines of "Tell Him" by the The Exciters (I know something about love, you've got to want it bad) as
"I know something about love, I've got a woman in bed"
Not a Mondegreen, but I only recently worked out that the line in Piano Man about putting "bread in my jar" referred to money, not you know, actual slices of bread. I couldn't work out why Billy Joel wasn't more annoyed about it.
I'm 36, no excuse.
