Head-in-Vice...
Another good expression I heard about law school was from the lady in charge of student programs at one of the big firms in Ottawa.

She said something like "first year law school is where they put your head in a vice, and crank it around until your view of the world is never the same again."
I've mentioned this to a few of my "collegues" (i.e. fellow law students) and I don't think that any of them have disagreed with me.
