I haven't thought David Letterman was funny for a years, but I would stay up late to watch this.
That said, I wonder how Letterman would react if one of his guests asked him, "So how's your bastard daughter, Dave? Are you sure it's yours, or did A-Rod bang your ugly wife in the Yankees locker room?"
I'm sure there would be laughs and yuks all around.
Shirley MacLaine was right.
