That's a joke, right?

Harvard thinks not - Spitzer has been invited by the university to speak today.

On ethics.

Former Manhattan Madam Kristin Davis finds this amusing, so amusing she sent a letter to professor Lawrence Lessig, of Harvard's Safra Foundation Center for Ethics.

"This sounds fascinating and I would love to attend," Davis wrote of Spitzer's speech, "but the restrictions of my probation won't allow me to travel outside New York City.

"For nearly 5 years, I supplied Mr. Spitzer with high-priced escorts while he was both Attorney General and Governor. For this crime, I served four months on Rikers Island, had all of my assets confiscated and am now considered a sex offender on 5 years probation. Mr. Spitzer broke both state and federal laws and walked away free.

"I am greatly intrigued as to what Mr. Spitzer could contribute to an ethical discussion when as Chief Executive Law Enforcement Officer of NY he broke numerous laws for which he has yet to be punished. As Attorney General he went around arresting and making examples out of the same escort agencies he was frequenting."

Hmmm . . . Forget HBO's "Hookers from the Point," this is "Madams with a Point."

Because Davis is unable to participate in Spitzer's Q&A, her letter to Lessig also includes questions she would like him to be asked:

Two of our favorites:

"3. Is it ethical for you to tip off your favorite escort service days before a bust so that they may disappear?"

"4. Is it ethical to try to book an assignation with a escort under a fake name after you were banned by my agency for being abusive to women?"

Harvard may have invited the wrong person to talk.

Michael Jackson update

A "Thriller"-era silk-screened portrait of Michael Jackson by Andy Warhol sold for $812,500 Tuesday.

The money could have almost paid for Michael's Sept. 3 family funeral, which had a price tag of roughly $1 million, according to court documents.

The final tally included $855,730 to Forest Lawn for cemetery and funeral charges including the purchase of other plots within MJ's mausoleum.

Also listed were: $35,000 for burial garments; $1,975 for wardrobe for the family; $2,000 for usher costumes; $3,682 for framing of a photograph of Jackson next to the casket; $959 for embroidery; $11,716 for invitations and programs; $16,000 for flowers; $30,000 for cars and security; and $15,000 for a funeral designer. There was also a charge of $21,455 for the "funeral repast" at a restaurant after the ceremony.

OK, which is it?
