An elderly married couple scheduled their annual medical
examination on the same day so they could travel together. After
the examination, the doctor then said to the elderly man: "You
appear to be in good health. Do you have any medical concerns
that you would like to ask me?"
"In fact, I do," said the old man.
"After I have sex with my wife the first time, I am
usually hot and sweaty, and then, after I have sex with my wife
the second time, I'm usually cold and chilly."
After examining the elderly lady, the doctor said: "Everything
appears to be fine. Do you have any medical concerns that you
would like to discuss with me?"
The lady replied that she had no questions or concerns.
The doctor then asked: "Your husband had an unusual
concern. He claims that he is usually hot and sweaty after having
sex the first time with you and then cold and chilly after the
second time. Do you know why?"
"Oh that crazy old son of a bitch!" she replied.
"That's because the first time is usually in July and the
second time is usually in December!"
