Well, NIKNAK, how about this one:
Mr. Smith went to the Doctor's office to collect his wife's test results.
Receptionist: "I'm sorry, sir, but there has been a bit of a mix-up and we have a problem. When we sent the samples from your wife to the lab,
the samples from another Mrs. Smith were sent as well and we are now
uncertain which one is your wife's. Frankly, that's either bad or terrible."
Mr. Smith: "What do you mean?"
Receptionist: "Well, one Mrs. Smith has tested positive for Alzheimer
disease and the other for AIDS. We cannot tell which is your wife."
Mr Smith: "That's terrible! What am I supposed to do now?"
Receptionist: "The doctor recommends that you drop your wife off in the
middle of town and if she finds her way home, don't f*** her.
