Weirdest pain? Anesthetic. I smashed a window and got a pretty nasty cut on my hand - only missed the tendons etc. by a tiny amount - but I didn't feel any pain. It didn't hurt when we bandaged it up, when we went to the hospital, when we waited there for several hours - didn't hurt one darned bit, until someone stuck a needle into it to anesthetise.

But that was far from the worst. That was just a bit of burning liquid in an open wound. Nothing compared to getting injections in the roof of the mouth. Holy god. I'm sure it would be worse to get teeth removed without anesthetic, but it's difficult to imagine that much pain. I developed a fear of injections in my mouth that lasted for about eight years after that, and it still persists, though I can now overcome it somewhat.
