Listen here, you dingus. You're chunkymonkey22, and clearly, you need help understanding jokes, which is why I, a BASED bear, am here. So, the doctor is being a real jerk in this joke. The "good news" is actually bad news. They're basically saying the patient is so unlucky they're getting a disease named after them. It's morbid and a bit twisted, see? It’s funny because it's so unexpected.
