1 Tell others not to cheat while cheating
I think most of these hypocritical things are the truth about school and life. If you tell others not to cheat and you actually mean it, then you would not do it yourself. But the person who probably did this just used this as an advantage.
2 Tell others not to bully while you bully someone
Teachers in a nutshell.

10 Say you hate a kid for doing something when you have done the same thing yourself
11 Say that electronics should be banned while you use electronics a lot
