Some journalism instructor I am. Today's top story all over the Fourth Estate: Deep Throat is finally revealed, and I tell everyone not to think about it right now, we've got a really important test to take. Hearst would throttle me alive.

Don't bother looking to me for links and what not: just pick up any newspaper in the country. The news is out: FBI Agent Mark Felt, who denied numerous times that he was Deep Throat (once even in his memoirs, published in 1978), was the cigarette-smoking guy in the underground parking garage.

The Tribune's lead: The world's most famous anonymous news source outed himself Tuesday.

The New York Times: Deep Throat, the mystery man who reigned as Washington's best-kept secret source for more than 30 years, was not just any shadowy, cigarette-smoking tipster in a raincoat. He was the No. 2 official of the F.B.I., W. Mark Felt, who helped The Washington Post unravel the Watergate scandal and the presidency of Richard M. Nixon, a feat that he lived to see disclosed on Tuesday, frail but smiling at 91.

From the Washington Post: For three decades, former FBI official W. Mark Felt lived with one of the greatest secrets in journalism history.

And from my afternoon class: "Everyone put away those newspapers and take out a Number Two pencil. These scan trons aren't going to finish themselves, people."

Just great. Now, when Felt does die (Woodward's stipulation for giving up his identity), he'll haunt me but good.
