Good News and Bad News
Ben goes to see his doctor because he wasn't feeling too well. After examining him, the doctor takes some samples from Ben and asks him to come back the following week for the results.
When Ben returns, his doctor tells him, "Well, I have some good news and some bad news. What do you want to hear first?"
Ben replies, "Let me know the good news first."
"Okay," says the doctor, "they're going to name the disease after you."
