I finally get it. I was at a friends place and he was flipping channels and stopped at Spinal Tap for a couple of seconds until his wife said NO we are not watching that. Anyways, it was just long enough to hear the stupid-clever line. I laughed out loud but I was the only one who got the joke. I tried to explain but for people who don't participate in any of the on-line forums... well they didn't get it. But I finally did. Good work, Shannon!
