My music teacher at Catholic school (yes, music class. We had to sing songs and play recorders all the time) in 4th and 5th grade made us do the same thing with the glossary in the back of the music book. However, the punishment was dished out at the class level; she'd threaten us if the entire class was acting up and would indiscriminantly administer the toil to everyone. We also had to do the whole thing, rather than just sections, but that's not asking for entirely too much since an elementary school music textbook's glossary didn't quite measure up to the gargantuan size of most dictionaries.

We all got terrible pains in our hands afterwards. But it wasn't any worse than the essays we had to write if we seriously misbehaved. I remember doing some terribly heinous deed at one point in time (probably when I erased the name on someone's floppy disk and wrote something a bit less flattering in place) and writing about how Satan made me do it or somesuch bullshit in detention. I didn't take it seriously, though; I just wanted to take up more space and disturb my superiors if they ever cared to actually read the damn thing.

But anyways, I digress...
