A Greek and a Frenchman sit down at the same bar one evening, and after a few rounds of beer, they begin amicably chatting, first about the occasional state of things in their respective countries.

Eventually as the night progresses they descend into debating which country has done the most for the rest of the world and, naturally, slide into sniping back and forth into ever greater and more magnanimous gestures toward the end.

At last, the Greek shoves up to his feet and announces before the rest of the bar, "My people invented sex!"

Stunned silence descends upon the environment at this, and for several seconds the Frenchman gives it some thought, before smiling and nodding his head and then answering,

"And mine introduced it to women."
