Tina Fey does an improv scene with David Letterman, swiftly owns him

There’s nothing worse than bad improv, and it’s no stretch to say that most improv is bad improv.

Now, in a preview for Fey’s May 4th appearance on My Next Guest Needs No Introduction With David Letterman, the comedian gets to flaunt her formidable chops in a short scene with Letterman himself.
