An Eagleville Valedictorian Abe Stokla had his diploma withheld after making some comments about his school during his graduation speech:
What is the controversy about?

“You have given us the minimum required attention and education to master any station at any McDonald’s anywhere. For that we think you. Of course, I’m only kidding. Eagleville is a fine institute of higher learning, with superb faculty and staff.”

However the audience never heard that part of his speech. School principal Rhonda Holton killed the microphone because it deviated from the speech originally approved by school administrators. She said that it implied that the high school doesn’t offer quality education.
Holton is on some type of power trip. This is a high school graduation, not a speech to the U.N. Rhonda, get off your high horse and welcome back to earth. As a result of your decision more people have heard Stoka’s comments than would have heard it on graduation night. Your decision shows a lack of openmindness and a lack of respect for free speech. His comments were not meant to be derogatory toward the school; it was meant as a joke.
Somehow this reminds me of some dialogue from my favorite movie:

Ed Rooney: I don’t trust this kid any further than I can throw him.
Grace: Well, with your bad knee Ed, you shouldn’t throw anybody… Its true.
Ed Rooney: What is so dangerous about a character like Ferris Bueller is he gives good kids bad ideas.
Grace: Mmm-hmm.
Ed Rooney: Last thing I need at this point in my career is fifteen hundred Ferris Bueller disciples running around these halls. He jeopardizes my ability to effectivley govern this student body.
Grace: Well, makes you look like a [jerk] is what he does, Ed.

Update 5/28/2005:
Eagleville principal: Valedictorian misled: Holton says he promised to leave bad statements out
