Disgraced unnyman of late night David Letterman used a portion of last night’s Late Show to extend an apology to his wife Regina and series staff after last week’s bombshell revelation that comedian has had sexual relationships with staffers over the years.

During a Late Show taping yesterday, Dave publicly apologized to his wife for cheating on her before they were married.

Monday’s taping was Letterman’s first since announcing a $2 million attempt to extort him with info over the staff sex secrets last Thursday.

What do you think of this apology, guys? Is he sincere?

“I’m terribly sorry that I put the staff in that position. Inadvertently, I just wasn’t thinking ahead. And, moreover, the staff here has been wonderfully supportive to me, not just through this furor, but through all the years that we’ve been on television and especially all the years here at CBS, so, again, my thanks to the staff for, once again, putting up with something stupid I’ve gotten myself involved in,” the 62-year-old said Monday.

“Now the other thing is my wife, Regina. She has been horribly hurt by my behavior, and when something happens like that, if you hurt a person and it’s your responsibility, you try to fix it. And at that point, there’s only two things that can happen: either you’re going to make some progress and get it fixed, or you’re going to fall short and perhaps not get it fixed, so let me tell you folks, I got my work cut out for me.”
