hmm. idk maybe when me and a buddy flipped a mule UTV. i busted my head open and his dad(a doc) gave me 6 stithies in their kitchen. i had a light concussion from it as well. but i hurt my side on the round tube by the seat. also have had 2 other concussions. and have had atvs flip and land on me. been flipped off at 20mph and thrown into a tree. broke my toe one day.
but i think having the prongs from a taser taped to my back and going for a 5 second ride tops all the pain i have ever had!!
