There was a doctor and he was having an affair with his nurse, she came to him and said she was pregnant, he told her he would pay for her to go to Paris and have the baby so his wife wouldn't find out.
She said we'll how do I get in touch with you to let you know when the baby's born?
He told her to send a postcard saying sauerkraut.
Nine months later the doctor's wife calls him at work and says, we received the strangest postcard in the mail, he asked what did it say?
She read, sauerkraut, sauerkraut, sauerkraut, 2 with weiners one without.
