"I have great pride in taking Dick and Jane out of most school libraries. That is my greatest satisfaction."
There's been so much great Dr. Seuss stuff this week! I'd never run across that quote before.
Anyway, hop on over to mental_floss for a list of seven books written in response to children's books. (Some of them required some stretching, as I don't necessarily equate 'response' as 'parody', but oh, well. Way fun column anyway.)
