Are You,

 a compulsive bubble wrap popper?

 if the answer is yes this is the key chain for you,

the key chain has eight rubbery little bubble keys on it that "pop" when you press them, it is just the thing to while away all those hours you spend standing in line or waiting in offices, granted it will drive everyone around you nuts, but it will help keep your cool, but here is the bonus, every 100th pop is not a pop at all, but a random noise such as a booing, a bark, or an other sometimes rude noise, well I can see how that could be embarrassing, but anyway for compulsive poppers it is the way to go! available on Amazon.
