September 12, 2000 - This Is Spinal Tap Special Edition DVD is released

Andrew Jacobs here,

As I've previously mentioned more than a few times, prior to 2003 and Windy City Heat, 1984's This Is Spinal Tap held the title as the funniest movie that I'd ever seen in my entire life.  And on September 12, 2000 (per Amazon), it was released on DVD with the following extras:

an audio commentary track with Christopher Guest, Michael McKean and Harry Shearer performing in character throughout, commenting on the film entirely in their fictional alter-egos and often disapproving of how the film presents them
79 minutes of deleted scenes (some of which were not on the This Is Spinal Tap Criterion DVD released in 1998)
Spinal Tap: The Final Tour, the original 20 minute short they shot to pitch the film
Catching Up with Marty DiBergi (where it is revealed that the members of Spinal Tap were very disappointed in DiBergi for making a "hatchet job" of their film)
two trailers that feature Rob Reiner showing a film about cheese rolling (because Spinal Tap itself was still in the editing room)
a TV promo, Heavy Metal Memories, and six additional TV promos
music videos for "Hell Hole", "Gimme Some Money", "Listen to the Flower People" and "Big Bottom"
segments of Spinal Tap appearing on The Joe Franklin Show

Thus making it the funniest DVD that I've ever seen in my entire life.  Yes, even funnier than the Windy City Heat DVD and it's weak extras.
