I found this costume description on fastcompanys.com. I had to share it.
THE BLACKBERRY – Your head is where the display would be, and your arms stick out the sides of this detailed replica of the world’s most addictive PDA. The costume is wired to receive text messages at a rate of one every 38 seconds, forcing you to keep interrupting whoever you are talking to in order to text back. Eventually, you become fed up and, while everybody watches, you strip off your Blackberry (make sure to be wearing something underneath) and throw it to the ground, stomping on it with your heel. You will not be surprised when the room erupts in cheers. Note: Do not do this with the IPhone costume. It’s too expensive to destroy.
