Did you even know this had a name?

Mondegreen. Apparently when author Sylvia Wright was a child she heard the song snippet 'laid him on the green' as 'Lady Mondegreen'. The American Heritage® Dictionary defines a mondregreen thus: "A series of words that result from the mishearing or misinterpretation of a statement or song lyric." See, I'm not even making this up. The Who's song I'm Free contains the lyric 'And freedom tastes of reality'. I was sure they were singing 'I'm free of the chains of reality'. And when Carly Simon was singing about that vain guy and mentioned clouds in my coffee, I heard grounds in my coffee. I still think my way makes more sense. One mondregreen is so famous it became the title of an Ed McBain novel. Guess which one!
