Last Day of High School

[drexah]

So, my last day of actual classes end tomorrow. I only have to take three finals and they are all a joke and i will get them done by thurs. (one on wed. two on thurs). question is..what prank/thing should i do tomorrow to leave my mark. Keep in mind, i am currently on the lacrosse team and i can't do anything so serious that i will get suspended from school (in turn kicking me off the team for basically the rest of the year)

please discuss. thoughts/ideas or past experiences are welcome.
