Things not to do in school

Something I recently came across in another forum that I think we could enjoy here. Just post a list of things that should not be done in school or things that you would at least reccomend that you not do.

1: Yell incoming behind a vietnam veteran principal and throwing an apple (Ive heard of this done many times at my school for the past 20 or more years)

2: Sing devil went down to georgia too quietly for people to clearly hear you (someone picked out the word devil and thought I was chanting to satan with a bible on my desk even)

3: Get into an argument over which vampires are cooler Anne Rice or Stephenie Meyer vampires. The obvious answer is Anne Rice but some people are retarded.

4: Loudly sing Stephen Lynch songs.

5: Saying racist jokes inbetween classes in the halls.
