Letterman Blackmailed

" I know that you do some terrible terrible things and I can prove that you do these terrible things ... and sure enough what was contained in the package was proof that I do terrible, terrible things."

A punchline of its own?

Last night, David Letterman told a story of exhortation that probably won't make it into the screenplay that the blackmailer, a male CBS worker, wanted to write. Though it wasn't stated how the would-be-writer would blackmail Letterman and become a public figure following the autobiography of Letterman's sordid affairs, someone should have told him what all our mothers did.

You can't have your cake and eat it too.
