Abe goes to the doctor’s office to collect his wife Sara’s test results. The receptionist tells him, “I’m sorry but there’s been a bit of a mix-up. When we sent your wife’s samples to the lap, they got mixed up with the samples from another Mrs. Cohen and we don’t know which one is your wife’s. The bottom line is that the situation is either bad or not so bad.”
“What do you mean?” asks Abe.
“Well,” says the receptionist, “one Mrs. Cohen has tested positive for Alzheimer’s disease and the other for gingivitis. We can’t tell which is which.”
“That’s terrible,” says Abe. “Can you do the test again?”
“Normally, yes. But your health insurance policy won’t pay for these expensive tests more than once.”
“Well what should I do?” asks Abe.
The receptionist replies, “The doctor recommends that you drop your wife off in the middle of town. If she finds her way home, don’t borrow her toothbrush.”
