We had an interesting thread awhile back to the tune of "What's the oldest video you have that you recorded?" Today, I ask, "What's the rarest?" Something that you, yourself, taped off-air. Maybe an obscure special, a news event, some classic sign-on/sign-off or between programs continuity, a priceless blooper or major screw-up, etc. Something not commercially available (or only available in edited, truncated, or otherwise altered form) and that no one else you've encountered caught. The kind of thing that, when you pop it in now and then to watch, you say to yourself, "Man, I'm damn glad I thought to run a tape that day!"
