Greeks vs Italians

A Greek and Italian were arguing over who had the superior culture.
The Greek says, "We have the Parthenon.”
"Arching his eyebrows, the Italian replies, "We have the Coliseum.”
The Greek retorts, "We Greeks gave birth to advanced mathematics".
The Italian, nodding agreement, says, "But we built the Roman Empire."
And so on and so on until the Greek comes up with what he thinks will end the discussion.
With a flourish of finality he says, "We invented sex!"

The Italian replies, "That is true, but it was the Italians who introduced it to women."
