Amy Sedaris gives a 4am walking tour of her New York City neighborhood, the West Village, during David Letterman's unique tapedinthemiddleofthenight episode of The Late Show on May 14, 2004.

Since many have commented about the timing of the taping, here's the opening to a news piece from the Associated Press about the ONE TIME ONLY May 14, 2004 episode: "David Letterman will be staying up very late — or getting up really early — to tape a show next week at 4 a.m. 'We thought it would be cool, just something different to try,' said Rob Burnett, the Late Show executive producer. 'We've been doing the show for so long that anytime you can come up with something new it makes it interesting for us.'"
