On Thursday, David Letterman admitted that he had slept with a number of women who have worked for him.

His revelation came amid allegations that a TV producer had attempted to blackmail him for $2 million by threatening to reveal his affairs.

Here's the top 10 reasons why we think David Letterman is an idiot.

10. The women he slept with worked for him.
David Letterman admitted that he slept with females who worked for him, including Stephanie Birkitt, who was initially his intern, and then his assistant. It’s always a gray area when a boss sleeps with a subordinate, leaving open questions about coercion.

9. He had a girlfriend at the time.
Dave was with long-time girlfriend Regina Lasko (who had previously worked for him) at the time of these entanglements. His affair with Stephanie reportedly ended shortly after Regina gave birth to his son, Harry, in 2003. Dave and Regina (who he began dating back in 1986) wed in March this year.

8. He jeopardized his job, and if he's fired we'll have to watch Conan.
After losing out initially to Conan O’Brien when the red-haired comedian took over as host of the Tonight Show in June, Dave quickly overtook him in the ratings. But on Thursday night, when he admitted to the affairs, Dave also admitted that he hoped to protect his job. It remains to be seen whether CBS will impose any penalties on him, but earlier this year his contract was extended until August 2012.

7. She's almost 30 years younger than him.
Yes, his quintuple heart bypass surgery in 2000 gave him a new lease on life, but did he have to use his newfound energy to chase a much-younger woman around his desk?

6. He admitted that he fooled around with more than one woman on his staff.
Dave obviously identifies too closely with Bill Clinton.
