Geez, the pain of the former would be worse, so I'm gonna go with screwdriver in the knee.
Speaking of which, would you rather take an arrow in the knee (thus destroying any capability of yours to be an adventurer), or be forced to speak in "arrow in the knee" jokes for the rest of your life?
I have both, so no need to choose.
WYR live with "Link" always saying "EXCUSE ME PRINCESS!" everyday and everytime or with Optimus Prime saying "Hold on to your dreams, the future is built on dreams" just ONCE and when you really need it?
