1 Kyros: Yeah, yeah. Not a problem.
2 Alvissa: How do you keep doing that?
3 Kyros: I unmake the universe, then remake it the same, but with the Balrog dead.

I suspect wizards are kind of like the category theorists of pseudo-medieval fantasy settings.

On a slightly different note, if you want to see the ultimate in self-deprecating mathematical fields, try pointless topology.
