We all think we know the lyrics to our favorite songs, so it can be very startling (and a little embarrassing) when you find out you've been belting out the wrong lyrics all these years. You can imagine my dismay when I, like so many other people including #16 on this list, learned that the Eurythmics were not actually crooning about how sweet dreams are made of "cheese" (speak for yourselves, Eurythmics! Mine are 100% brie). Clearly I'm not the only person to have confidently sang the wrong lyrics to a popular song.
