I had this Philosophy professor that liked to Shock and Awe and I remember him giving us this whole list of book title as reading materials and that we had a week to finish reading all of it. 
We expect that we would be reading a lot of materials but 15 books in one week and each were about 300-500 pages long and not to mention very expensive. 
Yet we were first year college students and growing up not asking questions. 
Some of the folks bought the books, some borrowed and on the third day some complained that it was not humanly possibly. 
There it began that we should question and ask questions and not meekly accept things even if comes from a professor. That would be the start of our long life pursuit of knowledge and we have to thank him for it.

Had to laugh at this one.
