For that special date 11-11-11, NPR's All Songs Considered did a podcast based on the this clip from This is Spinal Tap.

No surprise - my thoughts went to education. I wondered about the ways I try to turn my teaching volume up to eleven. There are certainly times in my classroom where I want to REALLY impress upon my learners the importance of what we are exploring.
