When my sister and I were younger we believed the Paul Young song "Everytime you go away" was saying "Everytime you go away, you take a piece of *meat* with you." When our mom found out what we were singing and tried to correct us, we argued with her that ours was right because it made more sense...how can you take a piece of someone with you? The idea was disgusting to us and even if she were taking a piece of him with her, it would technically still be a piece of meat. Our mom didn't think that was very funny and would get mad at us every time we sang the song the wrong way.
