This implies having ever stripped a wire. Which, no.
Uh, no. Because I have opposable thumbs, and can use tools, including wirestrippers.
Yes, occasionally. Unplugged, obviously. Sometimes it's just easier that way, and besides, an outraged dentist is a good dentist.
Yes, always. Wire strippers are for the weak and vain, who think they're too GOOD to use their teeth. If God had meant us to use wire strippers he wouldn't have given us flat-edged front teeth.
YES AND I DON'T EVEN UNPLUG THE WIRE BECAUSE I AM HARDCORE. Purely by coincidence, I've been electrocuted so many times now I can't let my credit cards get within two feet of my torso or else the strip demagnetises.
