In theory, anti-stress balls help you when you are a bit :-| or XO, because squeezing them helps you release some inner anger and make you bit more :-D. Whatever. I hate these things.
Every time I try one I want to get a knife and cut them in little pieces, which is probably what I will do if someone gets me these for Xmas. Still, they look like a perfect stocking stuffer for just $US12. [Deviant Wear]
