End of school crazy

The graduates this year wrote stuff on everything then they scribbled curses all over one class and got them in trouble.
So, if you're still in school or uni, how would you like to end your studying years?
I want everyone to remember me in a nice way, even teachers, I'm thinking of surprising them with something unexpected of me... I wanna clear any issues between me and my friends.
And if you've already finished, how did you end your studying days??

This year the seniors spraypainted their names on a classroom wall (that was going to be knocked down anyway), covered the office with sticky notes, and two dressed up like Pack Man and ran around campus. =O

^^thats amazing lol. The people who left my school this year, all signed the street signs outside the school - they got battered lol. but it was worth it b/c most of the rest of the school signed too!

The graduates frm my skul this year wrote graffitti all over the classroom walls and spray painted stuff lik "We rock".
Iam want to remembered nicely by MOST of my teachers!
