VIDEO: TEACHERS WHO PWNED THEIR STUDENTS!

Teaching isn't easy and sometimes kids can be assholes. Its only natural that teachers would want to get some form of revenge. No one can steal a calculator as long as it's stuck to a brick – unless you want to make your life extremely difficult. Some teachers are even willing to climb through the air vents to catch students cheating, and no, we aren't exaggerating! But, nothing beats one teacher bringing an actual coffin to work to prove to his students that their test scores were so bad that they had him dead.

They know all of the excuses in the book and have probably used them once upon a time. Sometimes, the excuses came back to bite the student in the butt. Give the teachers a break, they deserve it! 

Besides, you never know what kind of prankster they might be – and you might have it coming your way.
