"SAUERKRAUT" joke

A man was having an affair. The woman involved
suddenly announced that
she had become pregnant. Not wanting his wife to find
out, he gave her
a large amount of money and asked her to go out of the
country, to
Germany to stay with friends, to wait out the
pregnancy and have the
baby.
"But how will you know when our baby is born?" she
asked.
"Well", he said, "After you've had the baby, just send
me a postcard
and write' sauerkraut' on the back".
Not knowing what else to do, she took the money and
went off to
Germany.
Six months went by and then one day the man's wife
called him at his
office. "Dear, you received a very strange postcard
in the mail
today", she explained. "I don't understand what it
means!"
"Just wait till I get home and I'll read it," he
replied.
Later that evening, the man read his postcard which
said:
"SAUERKRAUT, SAUERKRAUT, SAUERKRAUT, TWO WITH WIENERS,
ONE WITHOUT!"
