An elderly Jewish man is bumped by a car while crossing the street. He is seemingly unhurt, but his wife persuades him to go to the doctor, just in case.

He returns home, and his wife says -- "Nu, vos zogt der doktor?" ["So? What did the doctor say?"]

"Der doktor zogt az ich hob a flucky. " ["The doctor says I have a flucky."]

"Oy, gevalt! A flucky! Terrible! What do you do for a flucky?"

"I don't know -- he didn't say, and I forgot to ask."

Well, by this time the wife is in a state of high anxiety. She tells her neighbors "My husband was hit by a car, and now he has a flucky! I don't know what to do!"

Neighbor #1 says, "In the old country, when someone had a flucky, we always applied cold. Cold is the best thing for a flucky."

Neighbor #2 says, "What are you talking about? Cold is absolutely the worst thing you could do for a flucky!
We always applied heat, that's the only thing to do for a flucky."

Cold, heat! Oy! Now thoroughly agitated, the wife decides to call the doctor herself. "Doctor, please tell me, what's wrong with my husband?"

"I told him ... nothing's wrong. He got OFF LUCKY!"

Visit to the Doctor
An elderly married couple scheduled their medical examination on the same day so that they could answer any questions the doctor might have concerning their partner.

After the husband's exam, the doctor then said to the elderly man, "You appear to be in good health. Do you have any medical concern 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."

The doctor said that he would examine the wife, and then report back to the man. 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 nut", she replied. "That's because the first time is usually in July and the second time is usually in December!"
