There are some really interesting choices in that list, to wit:
The Bridges of Madison County
Dianetics
Valley of the Dolls
Of course, I have quarrel with including Green Eggs and Ham, the book that introduced me to reading.
The first two are included just because they make cheap jokes about them. I don't actually recall them referencing Valley of the Dolls but I've never read it so I would've missed a subtle one and at one point they were making topical jokes and got so far off script that they had to skip a bit.
What's funny is that the Prof. and Coach wrote/directed it, and they were the ones who kept taking if farther off while Matt desperately tried to claw his way back to the show.
