Stevie Wonder is playing a concert... And on the front row, after finishing the encore, an asian man shouts: ""Play a Jazz Chord."" So he agrees and does another Jazz encore, though after finishing, the same man shouts: ""Play a Jazz Chord"" so again, he agrees and does another encore, but again the man shouts: ""Play a Jazz Chord!"" So he says: ""I've been playing Jazz for the last twenty minutes!"" ""No!"" Says the man, he walks onto the stage, sits on the piano and starts singing: ""A Jazz Chord to say I rove you!""
