I had a substitute teacher, who, when he was a senior in highschool, wanted to see how long he could have 12 molar Hydrochloric acid solution (12 times the ammount of HCl as H20) without chickening out, a la Fight Club. As it turns out, acid continues to burn long after you wash it off. By the time it started hurting and he washed if off, it continued to burn a hole straight through his hand. He now has a hole between his thumb and pointer finger.
