Actual excerpts from college course evaluation forms [none that I taught, of course]:

1.  "The textbook is almost useless.  I use it to kill roaches in my room."

2.  "He teaches like Speedy Gonzalez on a caffeine high."

3.  "Help!  I've fallen asleep and I can't wake up!"

4.  "The recitation instructor would make a good parking lot attendant. Tries to tell you where to go, but you can never understand him."

5.  "The class is worthwhile because I need it for the degree."

6.  "Textbook is confusing; someone with a knowledge of English should proofread it."

7.  "Problem sets are a decoy to lure you away from potential exam material."

8.  "He is one of the best teachers I have had...He is well-organized, presents good lectures, and creates interest in the subject.  I hope my comments don't hurt his chances of getting tenure."

9.  "I would sit in class and stare out the window at the squirrels. They've got a cool nest in the tree."

10.  "Information was presented like a ruptured fire hose-spraying in all directions-no way to stop it."

11.  "I never bought the text.  My $60 was better spent on the Led Zeppelin CDs that I used while doing the problem sets."

12.  "The course was very thorough.  What wasn't covered in class was covered on the final exam."
