Disease memes

When I was a boy, I had a disease that required me to eat dirt three times a day in order to survive... It's a good thing my older brother told me about it.

A woman walks into a doctor's office. She schedules an appointment and sits down in the waiting room. When it's her turn to talk to the doctor, she describes all of her symptoms, and they're unlike anything he's heard before. The doctor runs a few tests and steps out of the room. He comes back later, and says, "Well, I have good news and bad news." The woman says, "I'll hear the good news first please." The doctor replies, "The good news is we're naming a disease after you!"

I almost had a joke about Parkinson's disease, but I was too shaken up to say it.
