Surgeons invited to dinner parties are often asked to carve the meat -- or worse yet, to watch the host carve while commenting on the surgeon's occupation. At one party, a surgeon friend was watching the carving while Harry, his host, kept up a running commentary: "How am I doing, doc? How do you like that technique?
I'd make a pretty good surgeon, don't you think?"
When the host finished and the slices of meat lay neatly on the serving platter, the surgeon spoke up: "Anybody can take them apart, Harry. Now lets see you put them back together again."
