Turn teaching up to 11

I read an article at the BBC about some twit who pointed out that it's useful to have a bad teacher at some point because it builds character. While true, not something that the chairman of the Office for Standards in Education (something British) should say out loud.

But far more important than the quality of children's education is what happens when you adjust the volume on the accompanying video. The sound range on this video is from 0 to 11. Yes, 11.

You can turn it up to 11. I suspect this is a basic feature, and any video on the BBC website can be turned up to 11. On half a dozen different clips, I found this to be the case.
