We’ve spent all weekend trying to wrap our head around why anyone, particularly a public official, would knowingly siphon work-related funds to satisfy personal fetishes.

To be fair, former Rep. Jesse L. Jackson Jr., D-Ill., has copped to being exhausted/bipolar/depressed since dropping from view last summer. But, as became apparent with the filing of an official plea deal Feb. 15 — a mea culpa acknowledging Jackson and his wife, Sandi, illegally directed about $750,000 in campaign funds during the past decade for personal expenses — Jackson has clearly been out of his mind for quite some time.

Some of his mind-boggling splurges include:

• $43,000 for a gold Rolex;
• $27,000 for Michael Jackson memorabilia, including a $4,600 fedora;
• $10,000 for Bruce Lee collectibles;
• $5,000 for a football signed by “American presidents.”

While we never condone embezzling, Jackson could have at least saved a few bucks on his road to professional ruin.

An absolute steal at $12.10 (shipping included!).

Or how about this realistic looking Michael Jackson chapeau?

I mean, it’s trumpeted as the “#1 choice of professional MJ impersonators.” And at only $124.99, he could have bought two (one for display/storage purposes, and one for stepping out).

Mind you, the former legislator does seem to be ahead of the curve on some of his wacky investments.

This sweaty lid, purportedly worn by the King of Pop during an Apollo Theater fundraiser hosted by former President Bill Clinton, is up for grabs for a cool $65,000.

And this NFL football, sporting Clinton’s solo John Hancock, is on the auction block for $995 more than the multi-POTUS-signed pigskin Jackson must now hand off to the feds as restitution.
