I vote Chocolate mousse as well. I agree with Adrian- this is inane.

One point, though- if your ball mouse starts having trouble moving, just clean out the rollers on the inside by scraping all the crap off of them. Makes the mouse good as new. Also, make sure your mousepad doesn't wear too thin- recently, my mousepad of six years wore too thin, and the rubber underneath began collecting on the mouse, and I had to discard both of them.

Just a little more boredom for everyone.
