One time a married man got his secretary pregnant. He thought it would be best if he sent her away to have the baby. As she was leaving she asked him what she should do when she has the baby to let him know the baby was okay. He told her to call him.
She then asked, "What if your wife answers the phone?"
And he replied, "We'll use a special code. If you and the baby are alright say sauerkraut."
A few months later when the man came home from work one day his wife said, "I got the strangest phone call today. Someone called and said, "Hello. Sauerkraut, sauerkraut, sauerkraut, two with weiners one without."
