A stress ball is a good way to burn the rage within when people are doing stupid stuff. The Anger Management Set gives you three stress balls to deal with each level of anger: “annoyed”, “pulling your hair out” and “about to kill someone”. The higher you go on the anger scale, the larger the ball and the angrier the expression you get.

Sitting on its base, you have a miniature aquarium with swimming fish to keep you company when you are spending hours surfing the net. If you ever get stressed out, just pull the ball off the base and throw it around or bounce it off the floor. When you feel sufficiently relieved, just replace it on the base and go about your business with your swimming fish back in place.

This ball is designed to relieve stress but it seems more likely to convert your stress into downright insanity. Just look a that crazy-ass thing. It laughs hysterically when you squeeze it too. It’s the kind of toy you worry about coming alive at night to cut your throat.

Have you been feeling stressed out lately? Before you go on a rampage, give Sigmund Freud‘s disembodied head a few squeezes. The tension will just melt away.

Looking at something as twisted as this makes you need to squeeze it. If it were a cute little animal it may have a chance, but trying to appeal to yet another goofy friend is just one more step on your way to adulthood. I guess once you admit your friends are losers your mental health has taken a turn for the better. Squeeze balls can be indicators of future performance.
