If having a USB drive resembling the bullet from a machine gun isn’t enough for you, perhaps this USB drive made to look like an actual machine gun would be better suited for you.  Don’t worry, it’s not quite as large as a machine gun, so it is somewhat portable.  Although I’d advise keeping it away from places like the airport, despite that it is small enough to fit into your pocket.

Even though it appears pocket-sized, I’m not sure it’d be very comfortable within your pocket.  These Machine Gun USB Drives look like they have plenty of small pieces to poke you with and even break off within your pockets.  However, you could just leave this 4GB drive on your desk.  You can purchase the drive for $22 through USB Geek, which isn’t too bad of a price for a 4GB drive.
