At a country-club party a young man was introduced to an attractive girl. Immediately she began flattering him outrageously. The guy liked the young lady, but was taken a bit aback by her fast and ardent pitch. He was amazed when after 30 minutes she seriously proposed marriage.
"Look," he said. "We only met a half hour ago. How can you be so sure? We know nothing about each other."
"You're wrong," she smiled. "For the past 5 years I've been working in the back of the bank where you have your account. I know all I need to know about you."
