Levity never hurt on a Friday. If you've never seen the mockumentary This is Spinal Tap, perhaps this will whet the appetite. A classic, from many of the people who went on to bring you Best in Show, Waiting for Guffman, A Mighty Wind and For Your Consideration.
Reminds me of when I got lost backstage at the Richfield Coliseum once. Except I actually ended up on stage.
