A man was very much in love with a woman. One day she told him that the next day was her birthday. He told her he would send her a bouquet of roses... one for each year of her life.
That evening he ordered twenty-one roses with instructions that they be delivered first thing the next morning. As the florist was preparing the order, he decided that since the young man was such a good customer, he would put an extra dozen roses in the bouquet.
The fellow never found out what made his girlfriend so angry with him.
