A man goes into his doctor's office to pick up his wife's test results. The resceptionist looks distressed and says " Mr Smith, theres been a slight mix up with the results. You see, yesterday we had two Mrs Smiths come in to have tests done and the urine samples got mixed up. All we know is that one Mrs Smith has Alzheimers and the other has Aids." "This is terrible." cries Mr Smith, "What do you suggest I do?" The girl thinks for a second and replies, "Take your wife into the middle of town and leave her there. If she finds her way home, DON'T SCREW HER"
