Getting hit by a car and breaking your leg and loosing 50% of the skin on your foot - that tickles. Or breaking your thumb after someone jumped on it - again made me smile. Or removing a pitchfor from your foot (went all the way through) - not as bad as the others. Or the dentist killing the nerve in my right eye tooth - drilled a hole to my gum and used a massive needle to kill the nerve - could feel it just below my eye - not so good. Or having a cut thats packed out with guaze not salined properly so when the nurse pulls the guaze out the meat comes with it, and then she uses tweezers to push it back in! All with no pain killer. Stiches and tooth filling with next to no pain killers - also good. Other than that I like everything else!!!!
