Can anyone find a video clip of a 1994 Top Ten List
about the history of plumbing issue "The History of Plumbing"

David Letterman used the History of Plumbing issue to make
a Top Ten reasons why somebody would read "The History of Plumbing" or something like that...

Even the jokes in written form would be useful if no video
clip remains. I have checked everywhere CBS.com and on the web...but this particular Top Ten List doesn't appear.

It would have been on the David Letterman show some day before April 15, 1994. I am willing to pay for the clip.

Thank you and I can be emailed at lee.shortridge@hotmail.com
