The original Chicago Tribune column is here. Like I say, I hope I misheard; what kind of reporter would mention the misattribution and not the true source? (I know, I know, all kinds of reporters would. But it's not OK.)
In the late 1990s, a manifesto falsely attributed to Kurt Vonnegut made the rounds of e-mail boxes. It came to be known as "Wear Sunscreen" — and even spawned a hit music video from movie director Baz Luhrmann. A similar, but more vicious, manifesto is now going viral. It was penned by firebrand NYU professor Scott Galloway to a student who arrived to his class an hour late. We give this latest diatribe the Luhrmann-like musical treatment.
Update, 7:30 p.m.: It's even stranger than I thought; the report mentions that the original "essay" came from the Chicago Tribune, but it does indeed leave out the author's name (while mentioning Vonnegut and Luhrman!). Bizarre.
