Chaim goes to see his doctor because he isn’t feeling well. After examining him, the doctor takes some samples from Chaim and asks him to come back the following week for results.
When Chaim returns, his doctor tells him, “I have some good news and some bad news for you Chaim.”
Chaim replies, “OK, let me have the good news first.”
“OK,” says the doctor, “they’re going to name the disease after you.”
