How to make sure your cube is never cleaned

For my birthday Nicole and Melissa decorated my cube. Instead of birthday they do Halloween because I'm a Halloween freak, and so I can leave it up longer. This year, they did a body outline in tape on the floor and threw Halloween confetti all over everything - mostly the carpet. I noticed that my cube has not been vacuumed since. I wonder if it will ever get vacuumed again. Oh well. At least I know that if I drop an M&M one day it'll still be there the next to find and eat.
