Imagine shocking the testicles off an attacker with 20,000 volts while listening to Mozart’s Requiem! Finally, electrocution and music can go hand in hand with the new tactical Taser iProd attachment. Just snap it into place and make would-be muggers, annoying boyfriends, or squirrely-looking foreigners crap themselves senseless by hitting them with more electricity than their impacted bowels can stand.

But the battery life would totally suck for listening to music after that.

LoL Carry a large battery pack in your pocket and an AC adapter to charge after rendering the attack crispy.
OR!
