I don't think that Jay-Z is a comic book villain, but The Dallas Morning News may think so. In a recent video about LeBron James and Jay-Z, the latter is described as a "Music mongul" - I'm sure that they meant "mogul". After all, Mongul is this comic book villain.As you can see in the screen shot highlighted above, The Dallas Morning News F'd up the word mogul in the video's lower third. Stan--you, the Proofreader, any other individual with the smallest grain of cultural literacy and even (as evidenced by the caption in the above screen shot) The Dallas Morning News knows that Jay-Z is a music mogul, not a tyrannical comic book villain (though parallels between the two could certainly be drawn--fodder for a different blog) as this silly typo suggests.
The lesson that should be heeded here, by all newspapers trying to produce video content and by traditional T.V. news outlets, is to proofread those lower thirds and other graphics like it's your job, because, guess what? It is.
The Proofreader thanks Stan Kost for submitting the mistake.
