Yes, a really cool, awesome and evil plan Mwahahahahahahahahaha

Oh, thanks for explaining what a senior prank is, now I undersant what it is.

Let me see, I have to think about it. My hypothesis are:

- Mask of living dead and stalk people in school

- Lock people on the classrooms and then they have to leave by the windows

- If your school has a pool you can put ink on the water

For now I don't have more ideas. I hope have helped you. If meantime I have more ideas I'll tell you.
