Seriously, though, it's a good idea to have a circuit tester handy to be sure no electricity is flowing through the wires you're manipulating.
Next use a neon circuit tester to make sure that you've tripped the correct breaker and that the circuit is cold ( without power ).
To make the safety check, touch one probe of the circuit tester to the bare black wires and the other probe to the bare white wires.

Unscrew the solderless connectors, being careful not to touch the bare wires, then probe the wires with a circuit tester to make sure the power is indeed off.
While in-circuit testers are typically limited to testing the above devices, it is possible to add additional hardware to the test fixture to allow different solutions to be implemented.
For extra safety, use a circuit tester, basically a light bulb with two wire probes that you can get at a hardware store, and test all wires before you touch them.
