A doctor was having an affair with his nurse. Shortly after this started, she told him she was pregnant. Not wanting his wife to know, he gave the nurse a large sum of money and asked her to go to Germany and have the baby there.

“But how will I let you know the baby is born?” she asked.

He replied, “Just send me a postcard and write ‘sauerkraut’ on the back.”

Not knowing what else to do, the nurse took the money and flew to Germany. Six months went by and then one day the doctor’s wife called him at the office and explained, “Dear, you received a very strange postcard in the mail today and I don’t understand what it means.”

The doctor said, “Just wait until I get home and read it and I will explain it to you.”

Later that evening the doctor came home, read the postcard, fell to the floor with a heart attack and died.

So the wife picked up the card and read:

Sauerkraut, Sauerkraut, Sauerkraut, Sauerkraut
Two with wieners, two without
