i hate to say it, Dave, but that is not a good way to coil extension cords. yes it helps you get a clean coil, but bending the cable around your elbow like that can put permanent kinks in the cord. also, the extended use of that technique can break the wire inside depending on the gauge of the wire. i also wouldn't secure it like you describe at the end of the comic. i would use a small piece of rope or a velcro tie that is sold at Lowes or Home Depot to just tie off the cable in a loop. that way there is no damage to the cord itself. i feel like a complete nerd/a bit of an a-hole for saying all of this (especially since i love the punch line of that comic) but i coil extension cords every day for a rental company. it hurts us to see people coil them like that. i love the comic though.
I just had to refer to this strip to remember how to tie up a cord. And I'm not sure weather I should be proud that I actually took the time to actually tie up the cord or be ashamed that I didn't remember how to do it on my own...
