Kent: But there's already one big winner: Our state school
system, which gets fully half the profits from the
library.
Skinner: [talking with his teachers]
Just think what we can buy with that money...
History books that know how the Korean War came out.
Math books that don't have that base six crap in them!
And a state-of-the-art detention hall [holds up a scale
model] where children are held in place with magnets.
Teacher: [to no one in particular] Magnets. Always with the
magnets...
