I like dodyskin's bubblewrap link above. That seems to be the most worthless of the bunch because it truly reflects how we get caught up in worthless occupations sometimes--just zone out--and bubblewrap is a real culprit. The package comes, you open up the box, and remove the bubble wrap from around the item of some value (perhaps or not), but it's the bubblewrap that you can't resist and fortunately no one's in the house with you as you begin to pop it with your fingers and take off your shoes and pop it under your soles and find yourself counting how many bubbles you have left to pop and are very disappointed when it's all over although relieved, too, because you're late picking up your friend...
But with the bubblewrap link dody provided, well, heh! Forget the friend! You get to pop bubbles--and they keep coming back.
