Donny Deutsch, the CNBC host whose name sounds so deliciously close to douche, has been trying to pick up the pieces ever since his show went on hiatus and it was revealed that he had been having an affair with the wife of a hedge-fund manager, who then paid a P.I. to follow his wife around and caught the missus making kissy-face with the Douche . What a delightful surprise that must have been.

But an even better surprise was in store for the cuckold Andrew Sandler when he opened Deutcsh's new book, The Big Idea, and got a whiff of the new kind of "bond" advice the Douche was peddling.

"We've all heard the story. A guy marries his college sweetheart and she is the love of his life. She is completely devoted to him, and is willing to make every conceivable sacrifice to support his success. Hand in hand, they conquer the challenges of money, career and family," Deutsch writes. "And then he leaves her. He walks out the door, saying he's going to follow a new love. Don't let this happen to you."

Deutsch goes on: "No, I'm not giving marriage advice. I am, however, offering advice of the heart."

Now, this doesn't exactly count as an extreme case of dramatic irony, unfortunately, because Deutsch may just have some giant chip on his shoulder towards unfaithful men, and was just doing his part to even the playing field a little bit. Still, nobody wanted to take financial advice from the sleazeball, so why would you want to listen to him talk about "affairs of the heart" when only the first word applies to him?
