The Prank:

Thank Jim Halpert from The Office for this next instant classic. With a couple quick moves, you'll assume control of your colleague's cell phone -- and she'll have no idea what's going on.

The Process:

Bring a Bluetooth earpiece with you to work. When you spot an unattended cell phone, sneak over and pair your earpiece to the phone, making sure the device's Bluetooth functionality is activated.

The Final Product:

The next time your friend's phone rings, intercept the call and start chatting away, hands-free-style. Confusion and hilarity will ensue.
