Let's imagine it's 1820 and your leg has turned so green people think you're a quarter Hulk. You've taken your whiskey and hear your doctor walk in the door. Then you hear your audience walk in the room, followed by the booming, confident voice of the doctor demanding, "Gentlemen -- time me!" Suddenly, your lifesaving procedure is now performance art for Robert "The Flash" Liston. Which was probably pretty nerve wracking for everyone involved, considering he was known to swing his scalpel a bit this way and that in the heat of the moment. Sure, he was able to amputate a leg in 150 seconds, but he occasionally took the patient's testicles as well. Just cut them right off.
