When doctors say "Wow!"

I don't like impressing doctors. I hate it when they look at a swelling and say, "Wow, that's really big!" or at lab work and say, "Wow, that's really high!" or at a sprain and say, "Wow, look at all that bruising!" I don't want to hear any doctors I visit to say, "Wow!" I want them to play it cool. I want them to say things like, "Oh, that's nothing. I've seen a million just like that." Unless it's my urologist. He can say, "Wow, that's really big!" if he wants.
