The Late Movies: Classic Letterman

I was just alerted to this trove of classic David Letterman clips on YouTube. They appears to be transferred from VHS tapes, and give a glimpse of what late-night TV looked like in the 1980's. Ah, memories.
Dave Gets Help Making a Phone Call, January 1988
With a telephone technician, a receptionist skilled at dialing, a production assistant, legal counsel, a staff runner, and a fireman...what could possibly go wrong?
The NBC Bookmobile, February 1988
Dave gets a visit from a bookmobile on a forklift. "It's all in preparation for the upcoming Battle of the Network Bookmobiles."
Top Ten List & Supermarket Finds, July 1986
Wow, a reference to the USFL (United States Football League). Now that's dated.

Elvis Earmuffs. "Need to make a good impression on that important job interview?" Also an Elvis Presley Musical Jewelry Box.
Intro from Dave's First Month on the Air, 1982
A walk-and-talk on the way to the studio. You get to see Andy Rooney on the way, and an early appearance of Bud Melman.
