A mother had three daughters and, on their wedding, she tells each one of
them to write back about their marriage life. To avoid possible embarrassment
to their new husbands by openly discussing their love lives, the mother and
daughters agree to using newspaper advertisements as a "code" to let the
mother know how their love lives are going.

The first one gets married and the second day the letter arrives with a 
single message, simply: "MAXWELL COFFEE HOUSE" Mother got the newspaper and
checked the Maxwell Coffee House advertisement, and it says: "Satisfaction
to the last drop..." So, Mother is happy.

Then the second daughter gets married. After a week, there was amessage that
reads: "ROTHMAN'S MATTRESSES". So, Mother looks at the Rothman's Mattresses
ad, and it says: "FULL SIZE, KING SIZE" And Mother is happy.

Then it was the third one's wedding. Mother was anxious. After four weeks
came the message: "BRITISH AIRWAYS" And mother looks into the British Airways
ad, but this time shefainted.

The ad reads: "THREE TIMES A DAY, SEVEN DAYS A WEEK, BOTH WAYS."
