I wish I had a doctor with a good sense of humor. Like, I go in to complain that my leg hurts, and he says, "I've got just the thing." And the next thing I know, he injects me with Novocaine, and I wake up to find that he's cut the darn thing off. "Surprise!"
On second thought, I wouldn't wish that on anyone. Doctors with good senses of humor sometimes go a little bit too far.
