A Greek and an Irishman were sitting in a Starbuck's cafe one day discussing who had the superior culture.
Over triple lattes the Greek guy says, 'Well, we Greeks built the Parthenon,' arching his eyebrows.
The Irishman then replies, 'Well... it was the Irish that discovered the Summer and Winter Solstices.'
The Greek retorts, 'We Greeks gave birth to advanced mathematics.'
The Irishman, nodding in agreement, says, 'Irish were the ones who built the first timepieces and calendars.'
And so on until the Greek comes up with what he thinks will end the discussion. With a flourish of finality he says, 'The Greeks were the ones who invented sex!'
The Irishman replies, 'Indeed, that is true, but it was we Irish who introduced it to women.'
