Yesterday, David Letterman swallowed his foolish pride and confided to his studio audience that he cheated with more than one of his female staffers over the years. This is a good time to mention that Dave married his girlfriend of 23 years earlier this year.

This is more proof that men are cheating dogs by nature – and the workplace is the perfect environment for them to get a leg up. They don’t put “no fraternization” rules in employee contracts for nothing. 60% of men who cheat do so with a co-worker.

I’ve said it before, all a man needs is time and opportunity, and a small space to stand up in (like a supply closet). The workplace can be as sordid as a brothel at times. Any woman who thinks her man won’t cheat with the voluptuous single secretary is crazy.

A “48 Hours” producer was arrested yesterday for attempting to extort Letterman out of $2 million to conceal his cheating ways.
