S8E25: The Secret War of Lisa Simpson
It's not my nature to complain, but so far today,
we've had three movies, two filmstrips...
and an hour and a half of magazine time.
I just don't feel challenged.
Of course we could make things more challenging, Lisa,
but then the stupider students would be in here complaining,
furrowing their brows in a vain attempt to understand the situation.
