a) You Wank Taxi - I was in a car full of my mates driving somewhere when I taxi pulled out in front of me and I had to slam on my brakes. I blurted out You Wank Taxi and it became my nickname for a short while. Nowadays I tend to get called Darth especially at work.
b) Happy being called Darth if I'm honest
c) darthelvis is my on stage persona in my band Darth Elvis & the Imperials. Elvis didn't die he just turned to the dark side & the dark side has cookies!
