David Letterman reveals why he can't wait to be retired

As we all know, the great David Letterman will officially step down as host of the "Late Show" May 20.

He told "Late Late Show" guest host Regis Philbin Tuesday that he's not too upset about his upcoming retirement.

"Well, I'll tell you something. I can't wait for it to happen because I am sick and tired of people saying, 'Well, what are you going to do? What are you going to do?' I have no idea what I'm going to do," said David Letterman on "The Late Late Show."

Regis said Dave should create a new show and film from his own house once a week.

Dave didn't seem to keen on the idea, though. Hey, after working about five nights a week for 33 years, we don't exactly blame him.

He told Oprah back in 2013 he wouldn't have any regrets about leaving the late-night world behind:

"I will miss doing what I'm doing, but I won't feel like I have left anything on the table."

Dave has yet to announce any official plans for his retirement -- but we're sure he'll have plenty of notes for new "Late Show" host Stephen Colbert when he takes over.
